Nested Resolver Called via Field Resolver

[mikewzorek]

Hello,

I have an implementation based on #312 (comment) that was working in 0.17.6 however the "nested" resolver is no longer being called after upgrading to 1.0.0 and graphql to 15.3.0. Here's my implementation:

@ObjectType()
@InputType('SurveyResultInput')
export class SurveyResult {
  @Field()
  programId!: string;

  @Field()
  numberOfVotes!: number;
}

@Resolver(() => Survey)
export class SurveyResolver {
  @Query(() => Survey)
  async getCompletedSurvey(
    @Arg('propertyId', { nullable: false }) propertyId: string,
    @Arg('tenantBrandId', { nullable: false }) brandId: string,
    @Ctx() ctx: Context
  ) {
    try {
      const survey = await ctx.dataSources.surveyService.getSurveyResultsByPropertyAndTenant(
        propertyId,
        brandId
      );
      return survey;
    } catch (error) {
      throw new ApolloError(error);
    }
  }

  @FieldResolver(() => [SurveyResult])
  async results(@Root() survey: Survey, @Ctx() ctx: Context) {
    const resp = await ctx.dataSources.surveyService.getSurveyResultsByPropertyAndTenant(
      survey.propertyId,
      survey.brandId
    );
    return resp.results;
  }
}

@Resolver(() => SurveyResult)
export class SurveyResultResolver {
  @FieldResolver(() => Program)
  async program(@Root() result: SurveyResult, @Ctx() ctx: Context) {
    const program = await ctx.dataSources.matchmakingService.getProgramDetails(result.programId);
    return program;
  }
}

The program field resolver is no longer getting called despite the same graphql query.

  query getCompletedSurvey($propertyId: String!, $tenantBrandId: String!) {
    getCompletedSurvey(propertyId: $propertyId, tenantBrandId: $tenantBrandId) {
      results {
        programId
        numberOfVotes
        program {
          name
          nonprofit {
            name
          }
        }
      }
    }
  }

Thanks for the wonderful library and any help!

Are both SurveyResolver and SurveyResultResolver resolvers imported and used in resolvers array of buildSchema?

SurveyResultResolver was not. I added that and fixed it. Thanks for the help and quick reply!
