Unable to patch TrustFrameworkPolicy

Start by reproducing the request through graphServiceClient.TrustFramework.Policies[policyId] and inspect ToPatchRequestInformation alongside the TrustFramework Policies API operation. Verify whether the SDK should issue PUT or PATCH and confirm the resulting URI and method against the reported cpim.windows.net error. Done means the SDK request reaches the policy endpoint successfully and the reproduction completes without the controller or resource error.

Describe the bug

I am trying to write an automated system for adding and patching TrustFramework Policies using Microsoft.Identity.Web.GraphServiceClientBeta version 3.0.1 which is using Microsoft.Graph.Beta 5.78.0-preview.

I have successfully added a policy from the code provided by: Github msgraph-beta-sdk-dotnet issue 734 but I am unable to patch as it throws the following error:

No HTTP resource was found that matches the request URI 'https://cpim.windows.net/graph/trustFramework/policies('B2C_1A_TEST_01')'.","messageDetail":"No action was found on the controller 'trustframework' that matches the request.

Expected behavior

To patch a B2C Policy using the SDK. From looking at the api it indicates it should be a Put and not a Patch but there is no appropriate RequestInformation method on the graphServiceClient.TrustFramework.Policies[policyId] object.

How to reproduce

Run the following code:

Where:

• data: is a BinaryData object of the xml policy file.
• graphServiceClient: is a Beta.GraphServiceClient.
• policyId: is 'B2C_1A_TEST_01'

TrustFrameworkPolicyCollectionResponse? response = await graphServiceClient.TrustFramework.Policies.GetAsync();

TrustFrameworkPolicy? existingPolicy = response?.Value?.Where(x => x.Id == policyId).FirstOrDefault();

if (existingPolicy != null) {
  RequestInformation requestInformation = graphServiceClient.TrustFramework.Policies[policyId].ToPatchRequestInformation(existingPolicy);
  
  requestInformation.SetStreamContent(data.ToStream(), "application/xml");
  requestInformation.Headers.Add("Content-Type", "application/xml");
  
  Dictionary<string, ParsableFactory<IParsable>> errorMapping = new()
  {
      {"4XX", ODataError.CreateFromDiscriminatorValue},
      {"5XX", ODataError.CreateFromDiscriminatorValue},
  };
}

await graphServiceClient.RequestAdapter.SendNoContentAsync(requestInformation, errorMapping, cancellationToken);
