## Errors

| Code | Status | When | Fix |
|---|---|---|---|
| `not_connected` | 409 | Google Workspace isn't connected yet. | Connect it with google_connect. |
| `not_allowed` | 403 | The mailbox is not one the agent may act as. | Use a connected mailbox; the owner adds one by connecting again. |
| `not_found` | 404 | Google Workspace has no such message, event or file. | Search first and use its id. |
| `vendor_rejected` | 502 | Google refused: delegation is missing a scope, or Google said no. | Ask the Workspace admin to grant what the message names. |

The refusals every tool can give (401 key, 402 balance, 429 limits) are on the errors page: https://conecto.chat/docs/errors.md
