Referenced 'AssetCreateManyInput' populating with the wrong types

[gvonhagel]

Description

I have a custom mutation to create an Account with the option to simultaneously create or connect existing Assets to be bound to that Account. I provide a parameter in my mutation function called 'assets' that has a type of AssetCreateManyInput (which should be imported from my generated prisma.graphql schema). Generating the interfaces from my schema.graphql gives the wrong property types for AssetCreateManyInput.

Steps to reproduce

I have these types in my schema.graphql, that reflect and omit some values from my datamodel.graphql:

type Account {
  id: ID!
  company: String!
  isLockedOut: Boolean
  users: [User!]!
  assets: [Asset!]!
}

type Asset {
  assetId: String!
  assetType: AssetType
  users: [UserAssetConfig!]!
}

I have a mutation that creates an Account, User, and optionally connects/creates Assets

type Mutation {
  createAccount(email: String!, company: String!, accountType: AccountType, assets: AssetCreateManyInput): Account
}

My schema.graphql also imports the generated prisma.graphql file # import * from "./generated/prisma.graphql"

I then run graphql-resolver-codegen interfaces -s src/schema.graphql -o ./src/generated/resolvers.ts

Expected results

In resolvers.ts I expect to see something like what is generated in my prisma-client/index.ts:

export interface AssetCreateManyInput {
  create?: AssetCreateInput[] | AssetCreateInput;
  connect?: AssetWhereUniqueInput[] | AssetWhereUniqueInput;
}

Actual results

In resolvers.ts I actually see an interface that looks like this:

  export interface AssetCreateManyInput {
    create: string;
    connect: string;
  }

This causes type casting issues when I'm trying to write my mutation resolver in Typescript.

I can confirm this issue exists. I'm using both prisma-binding and graphqlgen.

Here's what prisma-binding generates for me:

export interface TagCreateManyWithoutParentInput {
  create?: TagCreateWithoutParentInput[] | TagCreateWithoutParentInput;
  connect?: TagWhereUniqueInput[] | TagWhereUniqueInput;
}

export interface TagCreateWithoutParentInput {
  value: String;
  text: String;
}

and here's what graphqlgen generates:

export interface TagCreateManyWithoutParentInput {
  create: string
  connect: string
}

which is incorrect.
