Using CiviCRM 5.37.2.
I'm trying to use the oath-client extension to do OAuth authentication of a Google Workspace (GSuite) account for bounce processing. The credentials are created on the Google side of things, and when I set up the Mail Account in CiviCRM and assign it to bounce processing, it works; "Save and Test" responds positively. And if I then go to the Scheduled Jobs and immediately execute the Bounces Fetcher job, it completes successfully.
However, after a little while, it fails to run, with this error:
Parameters parsed (and passed to API method):
a:1:{s:7:"version";i:3;}
Full message:
Finished execution of Bounces fetcher with result: Failure, Error message: Could not connect to MailStore for [the email address used for bounce processing]
Error message:
Required parameter not passed: "refresh_token"
Is this a problem with the oauth-client extension, or have I mis-set a setting somewhere in CiviCRM?
