Current behavior

When I use the include property, it doesn't find the resolvers.

BTW, I am using schema first approach.

Both endpoints appear at the Playground, but when I run any query, I get the following error:

{
  "errors": [
    {
      "message": "Cannot return null for non-nullable field Query.user.",
      "locations": [
        {
          "line": 2,
          "column": 3
        }
      ],
      "path": [
        "user"
      ],
      "extensions": {
        "code": "INTERNAL_SERVER_ERROR",
        "exception": {
          "stacktrace": [
            "Error: Cannot return null for non-nullable field Query.user.",
            "    at completeValue (/Users/gcherem/Source/nestjs/graphql-schema-first-problem/node_modules/graphql/execution/execute.js:595:13)",

            "    at /Users/gcherem/Source/nestjs/graphql-schema-first-problem/node_modules/apollo-server-core/dist/requestPipeline.js:8:71"
          ]
        }
      }
    }
  ],
  "data": null
}

If I comment out any GraphQLModule.forRoot and the include property of the other one, it works (but one endpoint with the whole schema).

Expected behavior

All queries should work.

Minimal reproduction of the problem with instructions

Create two GraphQLModule.forRoot with include property.

app.module.ts

import { Module } from '@nestjs/common';
import { GraphQLModule } from '@nestjs/graphql';
import { join } from 'path';

import { AdminModule } from './admin/admin.module';
import { PublicModule } from './public/public.module';

@Module({
  imports: [
    AdminModule,
    PublicModule,

    GraphQLModule.forRoot({
      debug: true,
      playground: true,
      path: '/admin',
      typePaths: ['src/admin/**/*.gql'],
      include: [AdminModule], // <--- here
      definitions: {
        path: join(process.cwd(), 'src/admin/graphql.schema.generated.ts'),
        outputAs: 'class',
      },
    }),

    GraphQLModule.forRoot({
      debug: true,
      playground: true,
      path: '/public',
      typePaths: ['src/public/**/*.gql'],
      include: [PublicModule], // <--- here
      definitions: {
        path: join(process.cwd(), 'src/public/graphql.schema.generated.ts'),
        outputAs: 'class',
      },
    }),

  ],
  controllers: [],
})
export class AppModule {}

admin.module.ts

import { Module } from '@nestjs/common';

import { UsersModule } from './users/users.module';

@Module({
  imports: [ UsersModule ],
})
export class AdminModule {}

public.module.ts

import { Module } from '@nestjs/common';

import { ProjectsModule } from './projects/projects.module';

@Module({
  imports: [ProjectsModule],
})
export class PublicModule {}

users.gql

type User {
  id: ID!
  name: String!
  email: String!
  password: String!
}

type Query {
  user(id: ID!): User!
}

users.module.ts

import { Module } from '@nestjs/common';
import { UsersResolver } from './users.resolver';

@Module({
  providers: [UsersResolver]
})
export class UsersModule {}

users.resolver.ts

import { Args, Mutation, Query, Resolver, Subscription } from '@nestjs/graphql';

import { User } from '../graphql.schema.generated';

@Resolver('User')
export class UsersResolver {

  @Query()
  user(@Args('id') id: string) {
    console.log('This line never runs!')
    return { id: '1', name: 'worked', email: 'worked', password: 'worked' };
  }
}

projects.gql

type Project {
  id: ID!
  name: String!
}

type Query {
  project(id: ID!): Project!
}

projects.module.ts

import { Module } from '@nestjs/common';
import { ProjectsResolver } from './projects.resolver';

@Module({
  providers: [ProjectsResolver]
})
export class ProjectsModule {}

projects.resolver.ts

import { Args, Query, Resolver } from '@nestjs/graphql';

@Resolver('Project')
export class ProjectsResolver {

  @Query()
  project(@Args('id') id: string) {
    console.log('This line never runs!')
    return { id: '1', name: 'worked' };
  }
}

[gcherem]

Hi @kamilmysliwiec, any update on it?

[gcherem]

After more tests I became it was due nested modules and I opened a more specific issue [#1148]

Please close this issue, thanks
