    "message": "Access denied",
    "hint": "Bitrix24 reports an access-rights refusal for tasks.task.result.update, not a scope error. The Bitrix24 user this call runs as lacks access; ask a portal admin to grant it, or call under a user who has it.",
    "cause": "b24_permission",

    "fix": {
      "action": "grant_b24_rights",
      "via": "portal_admin"
    }
  }
}
```

## Errors

| HTTP | Code | Description |
|------|-----|----------|
| 400 | `INVALID_PARAMS` | `id` is not a positive integer. Message: `id must be a positive safe integer` |
| 400 | `INVALID_PARAMS` | The body is not a JSON object or has no `fields` object. Message: `fields must be an object` |
| 401 | `MISSING_API_KEY` | The `X-Api-Key` header is missing |
| 401 | `TOKEN_MISSING` | The key has no Bitrix24 tokens |

| 403 | `SCOPE_DENIED` | The key has no `task` scope |
| 403 | `WRITE_BLOCKED_READONLY_KEY` | The key is in read-only mode. `error.details.switchUrl` contains the URL of the section where the mode is changed |
| 415 | `FST_ERR_CTP_INVALID_MEDIA_TYPE` | A non-empty body with a `Content-Type` other than `application/json` |
| 422 | `BITRIX_ERROR` | `fields` has no `text`, or `text` is an empty string. The reason is in `error.validation` |
