How can I enter parameters in Thunder Client in Visual Studio Code to call my Azure function?

Kim Strasser 2,186

I use this code on my iPad Air to call my Azure function DeleteAccountSendEmail:

  var result = await PlayFabCloudScriptAPI.ExecuteFunctionAsync(new ExecuteFunctionRequest()
  {
      Entity = new PlayFab.CloudScriptModels.EntityKey()
      {
          Id = entityid,
          Type = entitytype,
      },       
      FunctionName = "DeleteAccountSendEmail",
      FunctionParameter = new { SessionTicket = sessionticket, Deviceid = deviceid, Loginemail = loginemail, Language = language },
      GeneratePlayStreamEvent = true
  });

sessionticket, deviceid, loginemail and language are from type string.

How can I enter the same function parameters in Visual Studio Code in Thunder Client so that I can call my Azure function DeleteAccountSendEmail for testing purposes on my laptop?

I get an exception in this line when I call my function with your JSON example:

string playfabid = requestnew.CallerEntityProfile.Lineage.MasterPlayerAccountId;

System.NullReferenceException: 'Object reference not set to an instance of an object.' Functions.CloudScriptRequest<T>.CallerEntityProfile.get returned null.

    [Function("DeleteAccountSendEmail")]
    public async Task<HttpResponseData> DeleteAccountSendEmail(
        [HttpTrigger(AuthorizationLevel.Anonymous, "post", Route = null)] HttpRequestData req)
    {
        string body = await req.ReadAsStringAsync();
        log.LogInformation($"Raw request: {body}");

        var requestnew = JsonSerializer.Deserialize<CloudScriptRequest<DeleteAccountArgs>>(body, new JsonSerializerOptions { PropertyNameCaseInsensitive = true });
        string playfabid = requestnew.CallerEntityProfile.Lineage.MasterPlayerAccountId;
        log.LogInformation($"PlayFabId = {playfabid}");
        var args = requestnew?.FunctionArgument;
        string language = args?.Language;
        string loginemail = args?.Loginemail;
        log.LogInformation($"Language={language}, Loginemail={loginemail}");

My JSON was not correct. I changed my JSON and now I don´t get the exception anymore.

Hi @Kim Strasser ,

You can pass the parameters in JSON format as below:

Example:

{
  "SessionTicket": "ABC123",
  "Deviceid": "device-xyz",
  "Loginemail": "******@email.com",
  "Language": "en"
}

JSON was incorrect. After changing the JSON, exception is resolved.
