What causes this error?

The user’s login session tied to the access token has become invalid. This happens when a user logs out of Facebook, changes their password, or the session times out after an extended period.

How to fix it

1. Re-authenticate: Redirect the user through the Facebook Login flow again to get a fresh session and new access token.
2. Use long-lived tokens: Exchange short-lived tokens (which expire in ~1 hour) for long-lived tokens (which last ~60 days) using the /oauth/access_token endpoint.
3. Implement token refresh logic: Build automatic token refresh into your application so that expired sessions are handled gracefully without breaking your ad management workflows.
