Vague Authentication failure

I’m getting a vague authentication failure from GetApplicationDefaultAsync().

{“Error reading credential file from location C:\ArtofShell\Google\Vision\GoogleCred.json: Bad Data.\r\n\nPlease check the value of the Environment Variable GOOGLE_APPLICATION_CREDENTIALS”}

Here’s my code:

Environment.SetEnvironmentVariable("GOOGLE_APPLICATION_CREDENTIALS", @"C:\ArtofShell\Google\Vision\GoogleCred.json");
var credential = await GoogleCredential.GetApplicationDefaultAsync();

Repro steps:

1. I created a Service Account
2. I downloaded the credential file
3. I set the environment variable to the path of the credential file
4. Attempted to call GetApplicationDefaultAsync()

Our mistake – we thought we saw a pattern of failures after the latest release, but it turned out to be a problem in our own code. Please excuse the false alarm.

Hooray - glad it’s sorted. Chris’s recent change means that from 1.32.2 onwards, you won’t need to go to all the extra effort to get at the original exception. It’ll just be in the InnerException.
