Unable to access my resolver returned object, however, I can see its content, but accessing properties returns an undefined. Only solution I found is using Stringify/Parse on my value.
Using JSON Stringify then PARSE on my Object turns it to be readable, but this is a lame solution :)
const MonkeyResolver = {
Monkey: {
address: (data, args, context) => {
console.log({data}); // Returns the actual entire object (monkey>address)
console.log(data.address); // --> Returns undefined
const newData = JSON.stringify(data);
const parsedData = JSON.parse(newData);
console.log(data.address); // --> Returns the address
}
}
}
My expected object is such as :
Object(monkey)
address:
city
street
What did I misunderstand?
Solved : if the reference database model schema manager does not include the properties, graphql prevent using the properties. I had to check out my defined schemas and solved by adding the needed object properties.

I am testing PermissionDetail component which has graphql fragment, that is the data of node of PermissionTable component. I am getting a flow type error in this line when getting mock data from query const permissionDetail = data.viewPermissionScheme?.grantGroups[0].grantHolders?.edges[0].node.permission;.
Component hierarchy:
App -> PermissionTable (Paginated component fragment) -> PermissionDetail (fragment)
const TestRenderer = () => {
const data = useLazyLoadQuery<examplesPermissionQuery>(
graphql`
query examplesPermissionQuery #relay_test_operation {
viewPermission(id: "test-scheme-id") {
... on PermissionView {
groups {
holders(first: 10) {
edges {
node {
permission {
...permissionDetailsFragment
}
}
}
}
}
}
}
}
`,
{},
);
// Getting Flowtype Error here: Cannot get `data.viewPermission?.groups[0]` because an index signature declaring the expected key / value type is missing in null or undefined [1]
const permissionDetail =
data.viewPermissionScheme?.grantGroups[0].grantHolders?.edges[0].node.permission;
return permissionDetail ? (<PermissionDetails permissionDetail={permissionDetail}/>) : null;
};
What is the correct way to test such components? I am new to flow and graphql and relay. So need to understand the best way to test this.
I think the error is simply that data.viewPermission?.groups can be null or undefined. Therefore you are not allowed to access an(y) index on this property. One way to fix this is by using data.viewPermission?.groups?[0] to access the property.
You could also make groups non-nullable in your GraphQL schema. Some people like a lot of nullable fields because that allows the server to return as much partial data as possible in the case of an error. But for the developer this means that every field has to be checked for null.
I'm playing with Apollo Federation, and I'm using an entity from another service (File entity), in which this entity has the following resolver:
File: {
__resolveReference(reference, context) {
return null;
}
},
Now, in spite of hard-coding / returning null from the resolver, I still get the object containing specified fields, which are all null.
This is the query I'm sending:
Is this normal behavior?
Thanks!
This issue is migrated from a question on our Github account because we want the answer to be available to others. Here is the original question:
Hello,
Following is the InstanceQuery I tried
http://localhost:3000/3_0_1/Questionnaire/jamana/$graphql?query={id}
I am receiving back response as Cannot query field \"id\" on type \"Questionnaire_Query\"
So what is the right format I should try ?
https://build.fhir.org/graphql.html has a sample as http://test.fhir.org/r3/Patient/example/$graphql?query={name{text,given,family}}.Its working in their server. I cannot get the response When I try similarly in our graphql-fhir.
Original answer from Github:
We are using named queries since we are using express-graphql. I do not believe that is valid syntax. Also, the url provided does not seem to work, I just get an OperationOutcome saying the patient does not exist, which is not a valid GraphQL response.
Can you try changing your query from:
http://localhost:3000/3_0_1/Questionnaire/jamana/$graphql?query={id}
to this:
http://localhost:3000/3_0_1/Questionnaire/jamana/$graphql?query={Questionnaire{id}}
When writing the query, you need to provide the return type as part of the instance query. You should get a response that looks like similar to this(if you have implemented your resolver you will have data and not null):
{
"data": {
"Questionnaire": {
"id": null
}
}
}
and from a later comment:
If you are getting null then you are doing it correctly, but you haven't wrote a query or connected it to a data source. You still need to return the questionnaire in the resolver.
Where you are seeing this:
instance: {
name: 'Questionnaire',
path: '/3_0_1/Questionnaire/:id',
query: QuestionnaireInstanceQuery,
},
You are seeing the endpoint being registered with an id parameter, which is different from a GraphQL argument. This is just an express argument. If you navigate to the questionnaire/query.js file, you can see that the QuestionnaireInstanceQuery query has a different resolver than the standard QuestionnaireQuery. So in your questionnaire/resolver.js file, if you want both query and instance query to work, you need to implement both resolvers.
e.g.
// This is for the standard query
module.exports.getQuestionnaire = function getQuestionnaire(
root,
args,
context = {},
info,
) {
let { server, version, req, res } = context;
// Do query and return questionnaire
return {};
};
// This one is for a questionnaire instance
module.exports.getQuestionnaireInstance = function getQuestionnaireInstance(
root,
args,
context = {},
info,
) {
let { server, version, req, res } = context;
// req.params.id is your questionnaire id, use that for your query here
// queryQuestionnaireById does not exist, it is pseudo code
// you need to query your database here with the id
let questionnaire = queryQuestionnaireById(req.params.id);
// return the correct questionnaire here, default returns {},
// which is why you see null, because no data is returned
return questionnaire;
};
I want to update _parentcustomerid_value in the Contact entity (and some other) but I face such a problem - The property provided was of type System.Object, when the expected was of type System.Guid
I used this link to update entity attributes. Can anyone suggest me what to do? Maybe I'm doing something wrong or it's not possible to update ids.
For lookup attribute, you have to use single valued navigation property and not the lookup property.
entity["parentcustomerid_contact#odata.bind"] = "/contacts(DFE54660-37CD-E511-80DE-6C3BE5A831DC)"
Reference
The full code will look like this:
// define the data to update a record
var data =
{
"parentcustomerid_contact#odata.bind": "/contacts(DFE54660-37CD-E511-80DE-6C3BE5A831DC)"
}
// update the record
Xrm.WebApi.updateRecord("contact", "61a0e5b9-88df-e311-b8e5-6c3be5a8b200", data).then(
function success(result) {
console.log("Contact updated");
// perform operations on record update
},
function (error) {
console.log(error.message);
// handle error conditions
}
);

This must be simple and I'm being incredibly dense but I can't find an example to help me figure it out. I want to filter my list of tblAsset items by their assessmentId which is passed in through a parameter. I'm able to get the parameter value ok, but I'm not sure how to write the query.
My model is built from an existing Database using the Model creation wizard.
Thanks for any help!
public IEnumerable<tblAsset> GettblAssets()
{
NameValueCollection nvc = HttpUtility.ParseQueryString(Request.RequestUri.Query);
var assessmentId = nvc["aid"];
//limit the assets by assessmentId somehow and return
}
You could use the .Where extension method on the IQueryable<tblAsset> instance returned by your database:
public IEnumerable<tblAsset> GettblAssets()
{
NameValueCollection nvc = HttpUtility.ParseQueryString(Request.RequestUri.Query);
var assessmentId = nvc["aid"];
// TODO: you might need to adjust the property names of your model accordingly
// Also if the assessmentId property is an integer on your model type
// you will need to parse the value you read from the request to an integer
// using the int.Parse method
return db.tblAsset.Where(a => a.assessmentId == assessmentId);
}
