Having an error while trying to send OPTIONS to server.
The error:

{

    "code": 7,

    "message": "The service does not allow CORS traffic.",

    "details": [

        {

            "@type": "type.googleapis.com/google.rpc.DebugInfo",

            "stackEntries": ,

            "detail": "service_control"

        }

    ]

}

I get a normal response if I send GET request (throught postman).

The node server uses KOA.js with cors enabled

app.use(cors());

it works without endpoints, so I don't think there could be a problem in server.

What path did you use when sending OPTIONS? "/" or "/api/user"?

From your Swagger, you only setup "/api/user" path so OPTIONS only works for that path.
