question

Hi, I'm having trouble with FunctionExecutionContext<T>.CallerEntityProfile.DisplayName is null in Azure Functions (C#).

Here's the Azure Functions code in question.

public class Function1
{
    [FunctionName("Function1")]
    public string Run([HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] FunctionExecutionContext<string> request)
    {
        return request.CallerEntityProfile.DisplayName; // this is null
    }
}

* FunctionExecutionContext<T> uses this.
https://github.com/PlayFab/PlayFab-Samples/blob/master/Samples/CSharp/AzureFunctions/CS2AFHelperClasses.cs

I called this Azure Functions from a client using the C# SDK like this

var executeFunctionRequest = new ExecuteFunctionRequest
    {
        Entity = new PlayFab.CloudScriptModels.EntityKey()
        {
            Id = "41BBE5497F9DE458",
            Type = "title_player_account"
        },
        FunctionName = "FunctionA",
    };
    
await PlayFabCloudScriptAPI.ExecuteFunctionAsync(executeFunctionRequest);

At this time, Azure Functions received FunctionExecutionContext<T>.CallerEntityProfile.DisplayName is null.

{
    "CallerEntityProfile": {
        "AvatarUrl": "http://test.avatar.url",
        "Created": "2020-08-02T11:31:17.1484252Z",
        "DisplayName": null,
        "Entity": {
            "Id": "41BBE5497F9DE458",
            "Type": "title_player_account"
        },...

I can see the DisplayName in the GameManager. Is this a bug?
