I'm using Google API OAuth2 to authentificate my users (and I'm requesting a few scopes such as calendar). This part is working but when I'm trying to access the calendar, I'm getting the following error output:
An error occured while fetching events: { "error": { "errors": [ { "domain": "global", "reason": "authError", "message": "Invalid Credentials", "locationType": "header", "location": "Authorization" } ], "code": 401, "message": "Invalid Credentials" } }
Is there some way to get (extra) debugging info on the server or on google api side ?
