Google Cloud API credentials logged in full on http/401 response

Thank you for this integration. Does the job perfectly, and setting up with my own API credentials was a breeze.

Going through logs I've noticed the integration logs the full user provided client_id and client_secret if Google responds with a http/401. This likely doesn't pose a security risk as such as the credentials are wrong, but I'd say it's safer to assume worst-case scenario and redact those details before logging the error.
