auth: daily invalid_grant invalid_rapt forces re-auth for Workspace account

[TheRealJamesRussell]

Summary

I’m seeing daily forced re-auth with a Google Workspace account when using gog (Tasks and other services).
The stored token exists, but API calls fail with:

oauth2: "invalid_grant" "reauth related error (invalid_rapt)"

This happens roughly every day, not every 7 days.

Environment

• gog version: v0.11.0
• OS: Linux (WSL2)
• Account type: Google Workspace (@profittale.com)
• Keyring backend: file
• Services used: tasks,gmail,calendar,drive,contacts,docs,sheets

What I expected

Long-lived refresh token behavior (or at least not daily forced re-auth).

What happens

After successful auth, commands later fail with:

Get "https://tasks.googleapis.com/tasks/v1/users/@me/lists?...":
round trip: oauth2: "invalid_grant" "reauth related error (invalid_rapt)"
"https://support.google.com/a/answer/9368756"

Then I must re-auth again.

Repro steps

1. Run:
   gog auth add <workspace-email> --services tasks,gmail,calendar,drive,contacts,docs,sheets
2. Verify auth/token is present:
   gog auth list
3. Run:
   gog tasks lists --json --results-only
4. Works initially, then later fails with invalid_rapt and requires re-auth again.
