How to properly configure apollo graphql + node.js to google app engine

Question

I am trying to deploy a node + apollo server to google app engine so that I can call https://appspot/graphql. But I don't know how to achieve this.
https://localhost:8080/graphql runs successfully locally. I can use as endpoint to query. But https://appspot/graphql gives "GET query missing".

Problem solved by add playground:true, introspection: true to ApolloServer. Also whitelist all network.

Answer 1

I have not seen property any modules property, in Apollo Server config.

This is how I have setup my Apollo server:

const server = new ApolloServer({
            schema: mySchema, //This contains my consolidate schema, for a basic 
                              //setup, it can be an object containing typedefs 
                              // and resolvers or 
                              //complex schema.
            context: context,  
            playground: {       //if we want to keep the playground on in 
                                //Production. By default it is disabled.
                enabled: true,
                settings: {
                  "request.credentials": "include"
                }
            }
});

Moreover we need to provide path like following:

server.applyMiddleware({ app, path: '/somepath' });

So if you are looking run your server at some path then, it can be setup like above.
