I think both errors are related.
Thanks in advance.

I assume you are using the Google APIs Client Library for PHP. If so you can directly report this issue to the engineers working on this library.
I do see similar reports to this where the solution was a user-end code fix. 'Google_Service_Exception' indicates that the request you made was either not authenticated, had an invalid/malformed post body, and/or was made to an invalid URL.
Therefore I recommend you attempt to debug your code further in order to see what line of your code is throwing this error. Make sure you are using the library properly, and that your API request is correct. Also make sure you are using the latest version of the library.
