What this means in a real publishing workflow
Meta access depends on the permissions granted during OAuth and the assets managed by that Facebook identity. A token can be valid while the requested Page or Instagram account is no longer available to that user.
Recommended implementation
- Reconnect the correct Facebook identity through Postifys.
- Confirm the required Page and Instagram assets appear after refresh.
- Avoid storing Meta tokens inside n8n.
- Retry failed publishing only after the destination and permissions are confirmed.
How to verify the fix
Removing an admin role, changing a Page assignment, revoking the app, or changing a password can affect access. Reconnection is the safest recovery when refresh no longer restores the expected assets.
