I'm attempting to set the Flag on an e-mail using EWS Managed API 2 - however, I keep getting an error that I can't seem to get past.
I'm doing the following:
ExchangeService exchangeService = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
exchangeService.Url = new Uri(<ews url comes from Outlook JavaScript API>);
exchangeService.UseDefaultCredentials = false;
exchangeService.Credentials = new OAuthCredentials(<ews token comes from Outlook JavaScript API>);
And then a little later:
Item item = Item.Bind(exchangeService, new ItemId(<mail id comes from Outlook JavaScript API>), new PropertySet(ItemSchema.Flag));
item.Load();
item.Flag = new Flag() { FlagStatus = ItemFlagStatus.Flagged };
item.Update(ConflictResolutionMode.AutoResolve);
What am I missing?
I keep getting this error:
You must load or assign this property before you can read its value.
UPDATE: Ok, it turned out the this error was caused by some other code which has been corrected.
Now I'm getting this error instead:
The requested web method is unavailable to this caller or application.

When using RestSharp to query account details in your MailChimp account I get a "401: unauthorized" with "API key is missing", even though it clearly isn't!
We're using the same method to create our RestClient with several different methods, and in all requests it is working flawlessly. However, when we're trying to request the account details, meaning the RestRequest URI is empty, we get this weird error and message.
Examples:
private static RestClient CreateApi3Client(string apikey)
{
var client = new RestClient("https://us2.api.mailchimp.com/3.0");
client.Authenticator = new HttpBasicAuthenticator(null, apiKey);
return client;
}
public void TestCases() {
var client = CreateApi3Client(_account.MailChimpApiKey);
var req1 = new RestRequest($"lists/{_account.MailChimpList}/webhooks", Method.GET);
var res1 = client.Execute(req1); // works perfectly
var req2 = new RestRequest($"automations/{account.MailChimpTriggerEmail}/emails", Method.GET);
var res2 = client.Execute(req2); // no problem
var req3 = new RestRequest(Method.GET);
var res3 = client.Execute(req3); // will give 401, api key missing
var req4 = new RestRequest(string.Empty, Method.GET);
var res4 = client.Execute(req4); // same here, 401
}
When trying the api call in Postman all is well. https://us2.api.mailchimp.com/3.0, GET with basic auth gives me all the account information and when debugging in c# all looks identical.
I'm trying to decide whether to point blame to a bug in either RestSharp or MailChimp API. Has anyone had a similar problem?
After several hours we finally found what was causing this..
When RestSharp is making the request to https://us2.api.mailchimp.com/3.0/ it's opting to omit the trailing '/'
(even if you specifically add this in the RestRequest, like: new RestRequest("/", Method.GET))
so the request was made to https://us2.api.mailchimp.com/3.0
This caused a serverside redirect to 'https://us2.api.mailchimp.com/3.0/' (with the trailing '/') and for some reason this redirect scrubbed away the authentication header.
So we tried making a
new RestRequest("/", Method.GET)
with some parameters (req.AddParameter("fields", "email")) to make it not scrub the trailing '/', but this to was failing.
The only way we were able to "fool" RestSharp was to write it a bit less sexy like:
new RestRequest("/?fields=email", Method.GET)
Hi I have implemented Paypal Invoice, Express Checkout & Recurring Payments services using adaptive methods (NVP) call. It is working fine on my local system with sandbox account but not on development server and facing problem wherever I have called the paypal services based on request.

Will you please someone help me to get this out or suggest whats the reason behind this as it is working fine at local but not on development/production server.
Same kind of issue I am facing in case of express checkout and recurring payment methods too which is below:

Thanks in advance.
I have a servicestack service which when called via the browser (restful) Url ex:http://localhost:1616/myproducts, it works fine.
The service method has RedisCaching enabled. So first time it hits the data repository and caches it for subsequent use.
My problem is when I try calling it from a c# client via Soap12ServiceClient. It returns the below error:
Error in line 1 position 183. Expecting element '<target response>'
from namespace 'http://schemas.datacontract.org/2004/07/<target namespace>'..
Encountered 'Element' with name 'base64Binary',
namespace 'http://schemas.microsoft.com/2003/10/Serialization/'.
Below is my Client code:
var endpointURI = "http://mydevelopmentapi.serverhostingservices.com:1616/";
using (IServiceClient client = new Soap12ServiceClient(endpointURI))
{
var request = new ProductRequest { Param1 = "xy23432"};
client.Send<ProductResponse>(request);
}
It seems that the soapwsdl used is giving the problem, but I appear to have used the defaults as generated by servicestack..
Any help will be much appreciated.
Update
I was able over come this error by changing the cache code at the service end:
Code that returned error at client end:
return RequestContext.ToOptimizedResultUsingCache(this.CacheClient, cacheKey,
() =>
new ProductResponse(){CreateDate = DateTime.UtcNow,
products = new productRepository().Getproducts(request)
});
Code that works now:
var result = this.CacheClient.Get<ProductResponse>(cacheKey);
if (result == null)
{
this.CacheClient.Set<ProductResponse>(cacheKey, productResult);
result = productResult;
}
return result;
But I am still curious to know why the first method (RequestContext.ToOptimizedResultUsingCache) returned error at c# client?
But I am still curious to know why the first method (RequestContext.ToOptimizedResultUsingCache) returned error at c# client?
From what I can tell, the ToOptimizedResultUsingCache is trying to pull a specific format (xml, html, json, etc) out of the cache based on the RequestContext's ResponseContentType (see code here and here). When using the Soap12ServiceClient the ResponseContentType is text/html (not sure if this is correct/intentional within ServiceStack). So what ToOptimizedResultUsingCache is pulling out of the cache is a string of html. The html string is being returned to the Soap12ServiceClient and causing an exception.
By pulling directly out of the cache you are bypassing ToOptimizedResultUsingCache's 'format check' and returning something the Soap12ServiceClient can handle.
** If you are using Redis and creating your key with UrnId.Create method you should see a key like urn:ProductResponse:{yourkey}.html
Thanks for your response paaschpa.
I revisited the code and I was able to fix it. Since your response gave me the direction, I have accepted your answer. Below is my fix.
I moved the return statement from RequestContext to the response DTO.
Code which throws error when used via c# client (code was returning entire requestcontext):
return RequestContext.ToOptimizedResultUsingCache(this.CacheClient, cacheKey,
() =>
new ProductResponse(){CreateDate = DateTime.UtcNow,
products = new productRepository().Getproducts(request)
});
Fixed Code (return moved to response DTO):
RequestContext.ToOptimizedResultUsingCache(this.CacheClient, cacheKey,
() => {
return new ProductResponse(){CreateDate = DateTime.UtcNow,
products = new productRepository().Getproducts(request)
}
});
I am trying to write an activity in Google+ using the dotnet-client. The issue is that I can't seem to get the configuration of my client app correctly. According to the Google+ Sign-In configuration and this SO question we need to add the requestvisibleactions parameter. I did that but it did not work. I am using the scope https://www.googleapis.com/auth/plus.login and I even added the scope https://www.googleapis.com/auth/plus.moments.write but the insert still did not work.
This is what my request url looks like:
https://accounts.google.com/ServiceLogin?service=lso&passive=1209600&continue=https://accounts.google.com/o/oauth2/auth?scope%3Dhttps://www.googleapis.com/auth/plus.login%2Bhttps://www.googleapis.com/auth/plus.moments.write%26response_type%3Dcode%26redirect_uri%3Dhttp://localhost/%26state%3D%26requestvisibleactions%3Dhttp://schemas.google.com/AddActivity%26client_id%3D000.apps.googleusercontent.com%26request_visible_actions%3Dhttp://schemas.google.com/AddActivity%26hl%3Den%26from_login%3D1%26as%3D-1fbe06f1c6120f4d<mpl=popup&shdf=Cm4LEhF0aGlyZFBhcnR5TG9nb1VybBoADAsSFXRoaXJkUGFydHlEaXNwbGF5TmFtZRoHQ2hpa3V0bwwLEgZkb21haW4aB0NoaWt1dG8MCxIVdGhpcmRQYXJ0eURpc3BsYXlUeXBlGgdERUZBVUxUDBIDbHNvIhTeWybcoJ9pXSeN2t-k8A4SUbfhsygBMhQivAmfNSs_LkjXXZ7bPxilXgjMsQ&scc=1
As you can see from there that there is a request_visible_actions and I even added one that has no underscore in case I got the parameter wrong (requestvisibleactions).
Let me say that my app is being authenticated successfully by the API. I can get the user's profile after being authenticated and it is on the "insert moment" part that my app fails. My insert code:
var body = new Moment();
var target = new ItemScope();
target.Id = referenceId;
target.Image = image;
target.Type = "http://schemas.google.com/AddActivity";
target.Description = description;
target.Name = caption;
body.Target = target;
body.Type = "http://schemas.google.com/AddActivity";
var insert =
new MomentsResource.InsertRequest(
// this is a valid service instance as I am using this to query the user's profile
_plusService,
body,
id,
MomentsResource.Collection.Vault);
Moment result = null;
try
{
result = insert.Fetch();
}
catch (ThreadAbortException)
{
// User was not yet authenticated and is being forwarded to the authorization page.
throw;
}
catch (Google.GoogleApiRequestException requestEx)
{
// here I get a 401 Unauthorized error
}
catch (Exception ex)
{
} `
For the OAuth flow, there are two issues with your request:
request_visible_actions is what is passed to the OAuth v2 server (don't pass requestvisibleactions)
plus.moments.write is a deprecated scope, you only need to pass in plus.login
Make sure your project references the latest version of the Google+ .NET client library from here:
https://developers.google.com/resources/api-libraries/download/stable/plus/v1/csharp
I have created a project on GitHub showing a full server-side flow here:
https://github.com/gguuss/gplus_csharp_ssflow
As Brettj said, you should be using the Google+ Sign-in Button as demonstrated in the latest Google+ samples from here:
https://github.com/googleplus/gplus-quickstart-csharp
First, ensure you are requesting all of the activity types you're writing. You will know this is working because the authorization dialog will show "Make your app activity available via Google, visible to you and: [...]" below the text that starts with "This app would like to". I know you checked this but I'm 90% sure this is why you are getting the 401 error code. The following markup shows how to render the Google+ Sign-In button requesting access to Add activities.
<div id="gConnect">
<button class="g-signin"
data-scope="https://www.googleapis.com/auth/plus.login"
data-requestvisibleactions="http://schemas.google.com/AddActivity"
data-clientId="YOUR_CLIENT_ID"
data-accesstype="offline"
data-callback="onSignInCallback"
data-theme="dark"
data-cookiepolicy="single_host_origin">
</button>
Assuming you have a PlusService object with the correct activity type set in data-requestvisibleactions, the following code, which you should be able to copy/paste to see it work, concisely demonstrates writing moments using the .NET client and has been tested to work:
Moment body = new Moment();
ItemScope target = new ItemScope();
target.Id = "replacewithuniqueforaddtarget";
target.Image = "http://www.google.com/s2/static/images/GoogleyEyes.png";
target.Type = "";
target.Description = "The description for the activity";
target.Name = "An example of add activity";
body.Target = target;
body.Type = "http://schemas.google.com/AddActivity";
MomentsResource.InsertRequest insert =
new MomentsResource.InsertRequest(
_plusService,
body,
"me",
MomentsResource.Collection.Vault);
Moment wrote = insert.Fetch();
Note, I'm including Google.Apis.Plus.v1.Data for convenience.
Ah it's that simple! Maybe not? I am answering my own question and consequently accept it as the answer (after a few days of course) so others having the same issue may be guided. But I will definitely up-vote Gus' answer for it led me to the fix for my code.
So according to #class answer written above and as explained on his blog the key to successfully creating a moment is adding the request_visible_actions parameter. I did that but my request still failed and it is because I was missing an important thing. You need to add one more parameter and that is the access_type and it should be set to offline. The OAuth request, at a minimum, should look like: https://accounts.google.com/o/oauth2/auth?scope=https://www.googleapis.com/auth/plus.login&response_type=code&redirect_uri=http://localhost/&request_visible_actions=http://schemas.google.com/AddActivity&access_type=offline.
For the complete and correct client code you can get Gus' example here or download the entire dotnet client library including the source and sample and add what I added below. The most important thing that you should remember is modifying your AuthorizationServerDescription for the Google API. Here's my version of the authenticator:
public static OAuth2Authenticator<WebServerClient> CreateAuthenticator(
string clientId, string clientSecret)
{
if (string.IsNullOrWhiteSpace(clientId))
throw new ArgumentException("clientId cannot be empty");
if (string.IsNullOrWhiteSpace(clientSecret))
throw new ArgumentException("clientSecret cannot be empty");
var description = GoogleAuthenticationServer.Description;
var uri = description.AuthorizationEndpoint.AbsoluteUri;
// This is the one that has been documented on Gus' blog site
// and over at Google's (https://developers.google.com/+/web/signin/)
// This is not in the dotnetclient sample by the way
// and you need to understand how OAuth and DNOA works.
// I had this already, see my original post,
// I thought it will make my day.
if (uri.IndexOf("request_visible_actions") < 1)
{
var param = (uri.IndexOf('?') > 0) ? "&" : "?";
description.AuthorizationEndpoint = new Uri(
uri + param +
"request_visible_actions=http://schemas.google.com/AddActivity");
}
// This is what I have been missing!
// They forgot to tell us about this or did I just miss this somewhere?
uri = description.AuthorizationEndpoint.AbsoluteUri;
if (uri.IndexOf("offline") < 1)
{
var param = (uri.IndexOf('?') > 0) ? "&" : "?";
description.AuthorizationEndpoint =
new Uri(uri + param + "access_type=offline");
}
// Register the authenticator.
var provider = new WebServerClient(description)
{
ClientIdentifier = clientId,
ClientSecret = clientSecret,
};
var authenticator =
new OAuth2Authenticator<WebServerClient>(provider, GetAuthorization)
{ NoCaching = true };
return authenticator;
}
Without the access_type=offline my code never worked and it will never work. Now I wonder why? It would be good to have some explanation.
I'm really scratching my head with this. I'm trying to use the Dynamics CRM SDK to update an account record. No matter what I try, it's failing. Here goes.
Account sampleAccount = CrmAccount.GetAccountsBySubmissionCode(crmService, "ERZZUP").Single<Account>();
sampleAccount.Name = "AMC Edited";
crmService.Update(sampleAccount);
Gives the error: EntityState must be set to null, Created (for Create message) or Changed (for Update message)
XrmServiceContext ctx = new XrmServiceContext(crmService);
Account sampleAccount = CrmAccount.GetAccountsBySubmissionCode(crmService, "ERZZUP").Single<Account>();
sampleAccount.Name = "AMC Edited";
ctx.UpdateObject(sampleAccount);
ctx.SaveChanges();
Gives the error: The context is not currently tracking the 'account' entity.
XrmServiceContext ctx = new XrmServiceContext(crmService);
Account sampleAccount = CrmAccount.GetAccountsBySubmissionCode(crmService, "ERZZUP").Single<Account>();
sampleAccount.Name = "AMC Edited";
ctx.Attach(sampleAccount);
ctx.UpdateObject(sampleAccount);
ctx.SaveChanges();
Gives the error: The 'account' entity is already attached to a context.
For reference,
1. The Account object is created by the SDK Early Bound Code Generation Tool
2. crmService is the IOrganizationService connection object
3. GetAccounts ... performs a LINQ query and return an IEnumerable
Please help.
Thanks,
Chris.
Refer to http://msdn.microsoft.com/en-us/library/gg695783.aspx, particularly the "Multiple Data Contexts" part. It seems you're using multiple contexts to track the entities. The CrmAccount.GetAccountsBySubmissionCode method just hides this from you.
Make sure within the CrmAccount.GetAccountsBySubmissionCode method to dispose of the context/service before returning the IEnumerable<Account>, or make sure you use the same context/service to Update.
