Note the crash happens in your Logger.info call. We cannot print maps as is. Change #{credentials} to #{inspect(credentials)} and same for source line below. Does that help?

I could see in the earlier stack trace that you had "type" => "authorized_user" in your credentials. The credentials must be for the service account. You can create them for example like this:

$ gcloud iam service-accounts keys create --key-file-type=json --iam-account=... credentials.json
