GraphQL mapped types composition not displaying properties

[pedroaraujo1952]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

1. Use nest-cli.json compilerOptions.builder.swc:true compilerOptions.typeCheck:true
2. Import metadata.ts file in GraphQLModule config
3. Use a composition of GraphQL Mapped Types to a class with @InputType() decorator

@InputType()
export class UpdateInput extends PartialType(
  // PickType(CreateInput, ['description'] as const),
  // or any other mapped type like:
  OmitType(CreateInput, ['omitUpdateProperty'] as const),
) {
  @IsNumber()
  id: number;
}

4. The generated schema (code first aproach) generate the type for the input without the properties from CreateInput class

input CreateInput {
  name: String!
  description: String!
  omitUpdateProperty: String!
}

input UpdateInput {
  id: Float!
}

5. Using compilerOptions.builder.tsc:true works fine

Minimum reproduction code

https://github.com/pedroaraujo1952/nestjs-gql-mapped-types-error

Steps to reproduce

1. npm ci
2. npm run start:dev or npm run start

Expected behavior

Expected generated schema.gql:

input CreateInput {
  name: String!
  description: String!
  omitUpdateProperty: String!
}

input UpdateInput {
  name: String
  description: String
  id: Float!
}
