NestJS 5 GraphQL错误查询在解析器中定义，但不在架构中定义

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.
