Refresh token expiring? Error: 16 UNAUTHENTICATED: Failed to retrieve auth metadata with error: invalid_grant

  code: 16,
  details: 'Failed to retrieve auth metadata with error: invalid_grant',
  metadata: Metadata { internalRepr: Map(0) {}, options: {} },
  note: 'Exception occurred in retry method that was not classified as transient'

It seems like this keeps happening every week or so, and I need to go through the process of getting a new refresh token every time from here, which then fixes the issue.

+1 can some of the lib authors please elaborate on this one?

Hi @sgpascoe – The refresh token helper tool is meant as a quick way to get started, not really as a permanent solution 😃

That said, based on Google Support’s response, it sounds like you’ll get longer-lived tokens if you change your Google Project’s publishing status (likely the one associated with the client_id you’re using in the helper tool).

Consider checking the helper tool’s source code – it shows just how simple it is to get new tokens. Certainly much faster than setting up a puppeteer scraper!
