@printjs have you imported the resolver? Are you printing the anything on your console?

[printjs]

@rgolea
Yes,I have imported the resolver like below.

@Module({
    controllers: [NoteController],
    providers: [NoteService, NoteResolver],
    exports: [NoteService],
})
export class NoteModule {}

I debug the program.I found request that com from 127.0.0.1:19985/graphaql into breakpointer and the program can print userid

I am facing this same problem right now.

[CDDelta]

I fixed my case. VSCode auto-imports imported the Query decorator from @nestjs/common rather than @nestjs/graphql.

[printjs]

Thank you but query come from @nestjs/graphql in my program @CDDelta

[rgolea]

@printjs can you share with me the code? I can look and see if I can help.

[printjs]

@rgolea thank you. My project in https://github.com/printjs/graphql_ts and you just run npm i & npm run start. next step is visit localhost:3000/graphql

thank you very much.

[rgolea]

@printjs this is weird... mine prints... Try reinstalling the project and updating your node version and your typescript version.

[printjs]

@rgolea I'm so sorry.I give you wrong address.
Sorry, wasted your time.

The correct address is https://github.com/printjs/corgicherry.
You can run npm i & npm run start and visit http://127.0.0.1:19885/graphql

the graphql file is src/graphql/note/note.gql and the resolver file is note.resolver.ts in src/modules/notes/note.resolver.ts

I'm so sorry for give you wrong address.

[printjs]

I resolve the problem.Due to the interception change the data struct.

[val-samonte]

sorry not that im ranting, i was also a victim of wrong imports in vscode and i spent 3-4 hours scratching my head trying to figure out the problem. i think at least an effort to improve the nestjs/graphql docs and add a warning section about this problem would prevent someone encountering this

[loki29pl]

If someone has trouble with no executing Query, check if your modules don't have the same name. This situation may lead to null return.

[Almaju]

In my case this was because I was only doing include: [WorkspacesModule] in GraphQL configuration. You actually need to import the module twice like:

@Module({
  imports: [
    WorkspacesModule,
    GraphQLModule.forRoot({
      typePaths: ['./**/*.graphql'],
      include: [WorkspacesModule],
    }),
  ],
  controllers: [AppController],
  providers: [AppService],
})
export class AppModule {}
