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

[sgpascoe]

  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.

But is avoiding this constant process not the entire purpose of a refresh token?
