I have try to setup apollo server with apollo gateway and graphql-module.  
This is my repo of this setup: [Graphql Demo](https://github.com/ParkerTran/graphql-demo)  
The server is running success but problem come when call api.  
My resolver

```auto
Query: {
    me() {
      return { id: '1', username: '@ava' };
    },
  },

```

My API call response:

The return value for API me is null. But it should return { id: ‘1’, username: ‘@ava’ }.  
Could you pls take a look on this and give me an advice? Thank you so much.

You’re creating two separate subgraph schemas. It looks like it was correct before. If you uncomment `subgraphSchema` and remove the call to `buildSubgraphSchema` here it works.

Thank you for reply.

I would like to add [Graphql Module](https://the-guild.dev/graphql/modules) to this setup. So i use buildSubgraphSchema to build schema from typedefs and resolver from config of graphql module.
