[BUG] Input Object type UserOKRsUpdateManyMutationInput must define one or more fields

[oceanlvr]

Describe the Bug

When I create a new model name UserOKRs, it's relation include one-to-many and many-to-one relation to another model.

Then run apollo server, error occurred while generating GraphQL schema.

It seems that schema builder not work as we expect:

// ERROR
  const schema = await tq.buildSchema({ resolvers: resolvers });

And the error is :

  Input Object type UserOKRsUpdateManyMutationInput must define one or more fields.
Please check the `details` property of the error to get more detailed info.
    at Function.generateFromMetadata (/Users/oceanlvr/oyx/github/jff-OKR/backend/node_modules/type-graphql/dist/schema/schema-generator.js:20:23)

I check the file in UserUpdateManyMutationInput.ts file, and found it is empty export class

import * as TypeGraphQL from "type-graphql";
import * as GraphQLScalars from "graphql-scalars";
import { Prisma } from "@prisma/client";
import { DecimalJSScalar } from "../../scalars";
import { NullableStringFieldUpdateOperationsInput } from "../inputs/NullableStringFieldUpdateOperationsInput";
import { StringFieldUpdateOperationsInput } from "../inputs/StringFieldUpdateOperationsInput";

@TypeGraphQL.InputType({
  isAbstract: true
})
export class UserUpdateManyMutationInput {
}

To Reproduce

here is my schema, when I add the new model UserOKRs, then run yarn run dev start a apollo server.

// This is your Prisma schema file,
// learn more about it in the docs: https://pris.ly/d/prisma-schema

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}

generator typegraphql {
  provider = "typegraphql-prisma"
  output   = "./generated/type-graphql"
}

model User {
  id    Int     @id @default(autoincrement())
  email String  @unique
  name  String?
  posts Post[]
}

model Post {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  title     String
  content   String?
  published Boolean  @default(false)
  viewCount Int      @default(0)
  author    User?    @relation(fields: [authorId], references: [id])
  authorId  Int?
}

model OKR {
  id         Int        @id @default(autoincrement())
  squence    Int?       @default(autoincrement())
  obj        Obj        @relation(fields: [objId], references: [id])
  kvs        KeyValue[]
  objId      Int        @unique
  keyValueId Int
+  UserOKRs   UserOKRs?  @relation(fields: [userOKRsId], references: [id])
+  userOKRsId Int?
}

model Obj {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  okr       OKR?
}

model KeyValue {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt
  okr       OKR      @relation(fields: [okrId], references: [id])
  okrId     Int
}

model TimeStap {
  id        Int        @id @default(autoincrement())
  startTime DateTime
  endTime   DateTime
  createdAt DateTime   @default(now())
  updatedAt DateTime   @updatedAt
+   userOkrs  UserOKRs[]
}

+ model UserOKRs {
+   id         Int       @id @default(autoincrement())
+   okrs       OKR[]
+   timeStapId Int?
+   TimeStap   TimeStap? @relation(fields: [timeStapId], references: [id])
+ }

the error comes out:

The problem is solved. Thanks.

Realize that the empty type is entered because there are no fields other than the relationship
