✕ [API Error: [{ "error": { "code": 403, "message": "The caller does not have permission", "errors": [ { "message": "The caller does not have permission", "domain": "global", "reason": "forbidden" } ], "status": "PERMISSION_DENIED" } } ]]

TL;DR

The most likely fix is to re-authenticate or re-authorize the OAuth token to resolve the "The caller does not have permission" error.

Guidance

• Verify the OAuth token is valid and not expired by checking the authentication flow and token refresh mechanism.
• Check the permissions and scopes assigned to the OAuth token to ensure they match the required permissions for the API call.
• Re-run the command with the --verbose flag to gather more detailed error messages or logs that may indicate the specific permission issue.
• Consider re-authenticating using the oauth-personal auth type to obtain a new token with the required permissions.

Notes

The issue may be specific to the auto-gemini-3 model version or the oauth-personal auth type, and further investigation is needed to determine the root cause.

Recommendation

Apply workaround: Re-authenticate using the oauth-personal auth type to obtain a new token with the required permissions, as the current token may be invalid or expired.
