The way we used to write unit test cases for GraphqlModules doesn't seem to work correctly after integrating GraphQLModules with TypeGraphql. If few Examples could be added as to how we should modify our test cases accordingly would be better.

Suppose i have a type defined like this:-

@ObjectType()
export class User {
  @Field({ nullable: true })
  images?: string;
}

and i have a resolver defined like this:-

@resolver(of => User)
export class UserResolver {
constructor() {}

@Query(returns => User)
async user(@Arg("userId") userId: string, @Arg("apiKey") apiKey:string) {
    console.log(`inside behance resolver----------------`);
    return {
        images: 'test'
    }
}

}

and finally graphqlmodule is generated like this -

export const userModule = new GraphQLModule({
providers: [UserResolver],
extraSchemas: () => [
buildSchemaSync({
resolvers: [
UserResolver
],
container: ({ context }) => context.injector
})
]
});

Everything seems to be in line with the examples that have been provided. But when i am querying it says to me:-
Cannot return null for non-nullable field Query.user.
