userProjectDenied constant

The request is denied because the caller does not have required permission on the user project "projects/123" or the user project is invalid. For more information, check the userProject System Parameters.

Example of an ErrorInfo when the caller is calling Cloud Storage service with insufficient permissions on the user project:

{ "reason": "USER_PROJECT_DENIED",
  "domain": "googleapis.com",
  "metadata": {
    "consumer": "projects/123",
    "service": "storage.googleapis.com"
  }
}
