NestJS 5 GraphQL Error Query defined in resolvers, but not in schema

Question

I'm getting an error similar to the error described in Query.products is defined in resolvers but not in schema but only when I push to Heroku. Here are the details:

// profile.graphql
type Profile {
  id: ID!
  version: String!
  // ...
}

type Query {
  profile(id: ID!): Profile
  profiles: [Profile]
}

// profiles.resolver.ts
import { Args, Query, Resolver } from '@nestjs/graphql'
import { Profile } from './profile.entity'

@Resolver('Profile')
export class ProfileResolver {
  @Query()
  public async profile(@Args('id') id: number) {
    return await Profile.findOne(id)
  }

  @Query()
  public async profiles() {
    return await Profile.find()
  }
}

Locally, I can run yarn start:dev and it works great. The application starts successfully and I can query my GraphQL endpoint without a problem.

When I push this to Heroku, the application never starts up.

Why do I get the error in production and not in development? What is happening that makes the GraphQL schema not register my profile query?

Answer 1

The difference between local and prod lends itself to Typescript. I found out that none of the .graphql files were being copied by Typescript so I used copyfiles to solve the issue after my dist folder was created.
