Troubleshooting

The OAuth grant was revoked or expired. Remove the connector in the client and add it again; approval happens in the browser. For agent tokens, a 401 means the token was revoked or has expired, and the fix is a new one.

The assistant reads whatever the last sync indexed, and the extension does the syncing. Open the Syla extension and press sync; new material is answerable within minutes of indexing.

The connection's scopes exclude it, which is working as designed. Assistants request the standard set; agent tokens carry only the scopes picked at minting, so a token made for scheduling will not show view_page.

It cannot be recovered, only replaced: Syla stores a hash, not the token. Mint a new one in Connections and revoke the old.

Back off and honour Retry-After. Sustained polling is the usual cause; whats_changed and changes_since exist precisely so an agent can ask “what moved” instead of re-reading everything on a timer.

founder@usesyla.app. Include the client (ChatGPT, Claude, your own agent) and what the failing call returned.
