6 years ago This happens when you pass an invalid ServiceAccountKey file. You can see how to download the Service Account Key in the tutorial I wrote in the README. Please check your Service Account Key File and eventually download it again.

I have an unhandled exception when I run the project:
{"Error creating credential from JSON. Unrecognized credential type ."}
Error is at this line: var result = client.SendAsync(message, cts.Token).GetAwaiter().GetResult();
and here is my stack trace:
