Google Cloud Endpoint at "/" Method does not exist

Question

 "code": 5,
 "message": "Method does not exist.",

  }
 ]
}

My Cloud Endpoints deployment seems to work fine except when trying to load the root path (at "/"). The endpoint appears in the console, but trying to load it outputs the error above.

I've searched all over but can only find one reference to it anywhere (on mobile now but will add it here when I find it again).

Google Cloud Endpoints does not currently support the root path at "/". The documentation will be updated to reflect this soon. https://cloud.google.com/endpoints/docs/openapi/openapi-limitations
