when I try to add\change the value of a custom lookup and then save it, I get this error:

ErrorCode: -2147185383
HexErrorCode: 0x80048d19
the field's logical and schema name is "ey_org_unit_hr_id" (both of them are identical).
I opened the post request that the form sends and this is what I found:
{"ey_org_unit_hr_id#odata.bind":"/ey_businessunits(91293b20-afb7-e611-bec8-0050568c00dc)",
"ey_org_unit_hr_id#OData.Community.Display.V1.FormattedValue":null,
"ey_s_name":"test555",
"ey_b_is_doctor_house":false,
"ey_b_is_route_service_requests":false,
"ey_b_real_branch":false,
"statuscode":1,
"statecode":0}
then I opened the metadata and found out that the NavigationalProperty Name of this field is different than what is used in the post request (ey_org_unit_hr_id is used in the request but the navigational property name is ey_ey_businessunit_ey_branch_hr which is also the name of the relationship).
Photo of the navigation property name
so i tried to send a post request using postman whith the currect NavigationProperty Name and it worked without an error.
Here is the request:
{"ey_ey_businessunit_ey_branch_hr#odata.bind":"/ey_businessunits(91293b20-afb7-e611-bec8-0050568c00dc)",
"ey_ey_businessunit_ey_branch_hr#OData.Community.Display.V1.FormattedValue":null,
"ey_s_name":"test555",
"ey_b_is_doctor_house":false,
"ey_b_is_route_service_requests":false,
"ey_b_real_branch":false,
"statuscode":1,
"statecode":0}
I thought about changing the navigational property name to what is used in the original post request but I don't know if I can change the metadata.
Try this property name: _ey_org_unit_hr_id_value.
You should check your error code at the below link.
https://learn.microsoft.com/en-us/power-apps/developer/data-platform/reference/web-service-error-codes
AFAIK, the 0x80048d19 code will be exposed by sending request with invalid data.
In my case, I got this error code when i sent request without header "Content-Type: application/json"
I hope this can be helpful to you

I am creating a webapi and just wondering whether I can replace the default error message in case of 400 Bad Request.
For example, in this url (http://localhost/api/values/4) 4 is the integer type but if I pass a string intentionally (e.g. http://localhost:35453/api/values/sss), I receive an error (400 Bad Request) in the following format:
{
"Message": "The request is invalid.",
"MessageDetail": "The parameters dictionary contains a null entry for parameter 'id' of non-nullable type 'System.Int32' for method 'System.Web.Http.IHttpActionResult Get(Int32)' in 'WebAp__DELETE.Controllers.ValuesController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter."
}
Is there any way I can replace this default error message with a custom error message of mine.
I have the following in one of my view models:
public char? MyChar { get; set }
I noticed there appears to be no client-side validation on the textbox for MyChar, and it's possible for a user to submit a string that is too long for this char to my controller (it simply doesn't bind and remains null).
So, I added the [MaxLength] annotation. Client-side validation now works as expected, but when I submit a valid value to the server, I get the following exception in my event logs:
Exception information:
Exception type: InvalidCastException
Exception message: Unable to cast object of type 'System.Char' to type 'System.Array'.
at System.ComponentModel.DataAnnotations.MaxLengthAttribute.IsValid(Object value)
How can I validate the max length of a char correctly both client-side and server-side?
What I've Tried
For now, I've created my own MaxLength attribute for it to work with char types, but it feels like a heavy approach.
I have an asp.net web api 2 application that provides data in JSON format for api clients. For GET api methods, an api client programmer who is using Java and C++ languages to call those GET method apis. However, for null-valued properties of JSON objects, the client programmer says he receives "null" (null in-quote string) for those properties. In SQL Server database for nvarchar (string) and datetime columns of different database tables, I save those null-valued columns as null as normal SQL server convention but not "null" string.
My question is what is the best way to let api client programmers know if a null-valued property is null to distinguish it from real "null" string, e.g. {"state": "null"} a literal string. Thanks in advance.
I have many GET method apis which returns null for null-valued properties of JSON objects.
I test my GET Api methods for null properties with Postman or Advanced Rest Client tool, I do not see those tool returns null in "null" (in-quote string) for null-valued properties: (here is state and closeddate properties)
{"firstname":"abc","lastname":"def","state":null,"birthdate":"1992-05-25T00:00:00","closeddate":null}
One of GET method api looks like:
[HttpGet]
public HttpResponseMessage GetUserInfo(int userid)
{
var user = _userService.GetUserInfo(userid);
var statusCode = _userService.StatusCode;
var errorCode = _userService.ErrorCode;
return _statusCode == HttpStatusCode.OK
? Request.CreateResponse(_statusCode, account)
: Request.CreateResponse(_statusCode, errorCode);
}
Since you are asking for an opinion, here's one from the creator of SlashDB API: when in doubt, leave it out.
In the JSON data format keys with null value can be omitted from the result.
The following API call returns a Customer record, which does not have a value in the Company field:
HTML rendering: http://demo.slashdb.com/db/Chinook/Customer/CustomerId/2.html
JSON rendering: http://demo.slashdb.com/db/Chinook/Customer/CustomerId/2.json
XML format is more formal about it because you can define a schema, which prescribes what is the allowed shape of data. In particular, an element (tag) could have a minOccurs=0 attribute to indicate its optionality, and/or a nillable=True to indicate that a tag could be present without a value (i.e. ). For completeness here's the same record in XML and its schema:
XML rendering: http://demo.slashdb.com/db/Chinook/Customer/CustomerId/2.html
XSD schema: http://demo.slashdb.com/db/Chinook/Customer.xsd
I'm using Spring form tags for filling form with values.
I have form backing object:
public class FormInfo {
public enum Status {ON, OFF}
private Satus status;
//getter setter
...
}
And in JSP Status enum presented like this:
<form:form commandObject="formInfo " ...>
<form:select path="status">
<form:option value="null" label="Please select"/>
<form:options/>
</form:select>
</form:form>
All works fine, i.e. default message and enum values are presented in <select>.
But the status field is not required, so I want allow user to leave Status field unselected. But if form submitted without selecting status field, then I get error:
error in object 'formInfo' on field 'status': rejected value [null];
How I can set enum to null when no values is selected?
Please note I'm using JSR 303 validation. And error described above is not happens automatically, I get this error message manually from following method BindingResult#getFieldErrors().
This is my controller code:
public void myMethod(#Valid #ModelAttribute("formInfo") FormInfo sourcingDetail, BindingResult bindingResult) {
if (bindingResult.hasErrors()) {
log.error("Error during validation is occurred." + bindingResult.getFieldErrors().toString()); // <-- this is error message
}
...
}
Also please note, I didn't set any JSR-303 annotation (like #NotNull) on status field.
UPDATE:
Almost full error message which I get from calling this method BindingResult#getFieldErrors() (explained above):
Error during validation is occurred.[Field error in object 'formInfo'
on field 'status': rejected value [null];
...
[Failed to convert property value of type 'java.lang.String' to
required type 'com.my.project.model.Status' for property 'status';
nested exception is java.lang.IllegalStateException: Cannot convert
value of type [java.lang.String] to required type
[com.my.project.model.Status] for property 'status': no matching
editors or conversion strategy found],
Looks like you have the same problem as i!.
There is a method in the controller that serves as a hook where you could specify how to transform the String values, that came from the HTTP request, to a concrete object!.
The method is called initBinder, and there you attach the right behavior to do the conversion properly. I am still researching, but so far, looks good.
Take a look at this :
Form Values to be Null instead of "" in Spring

Hope it helps to found the solution!

Hi when I try to do an Ajax post to my controller I keep getting this message:
The parameters dictionary contains a
null entry for parameter 'id' of
non-nullable type 'System.Int32' for
method 'System.Web.Mvc.JsonResult
GetContactsByDepartment(Int32)' in
'Intranet.Controllers.MyController'.
An optional parameter must be a
reference type, a nullable type, or be
declared as an optional parameter.
The method head looks like this: public JsonResult GetContactsByDepartment(int id)
What am I missing? I have ensured that the id is being passed through my Jquery ajax call.
Try to rename id to for example DepartmentID.
Probably an issue with your registered routes.
