What is the problem?

Union type definition is generated with a weird "id" suffix. Maybe there is a reason?

Consequently, some of our union type are generated in GraphQL (as we have an advanced code first pre-processing using CDK AppSync) like this:

input UpdatePayloadInput {
  Type1id: Type1Input
  Type2id: Type2Input
}

Reproduction Steps

Build a Union type:

    const TypeUnion = new appsync.UnionType("TypeUnion", {
      definition: [
        Type1,
        Type2,
      ],
    })


   console.log(TypeUnion.definition)

This gives out:

{
  Type1id: GraphqlType {
    type: 'INTERMEDIATE',
    // ...
    }
  },
  Type2id: GraphqlType {
    type: 'INTERMEDIATE',
    // ...
    }
  }
}

What did you expect to happen?

Definition does not contain the "id" suffix.

What actually happened?

"id" is appended to the union type definition.
