TypeError: outputType.fields is not iterable

[sk1122]

Bug description

I am prisma with postgresql with below schema

Debugged this error a little bit inside compile @prisma/client code and found this (this is a computer generated code though)

In selectionToFields(dmmf, selection, schemaField, path7, context3) function, we have this line of code inside reduce method on Object.entries(selection)

const field = outputType.fieldMap ? outputType.fieldMap[name] : outputType.fields.find((f) => f.name === name);

after console.log, we get this

{
  name: 'createOneID',
  args: [
    {
      name: 'data',
      isRequired: true,
      isNullable: false,
      inputTypes: [Array]
    }
  ],
  isNullable: false,
  outputType: {
    type: 'ID',
    namespace: 'model',
    location: 'outputObjectTypes',
    isList: false
  }
} 

If you look, outputType.type is a string but in other cases it is an object

How to reproduce

1. Copy my schema from above
2. Initialize postgresql database
3. run above create query with required params

Expected behavior

Should create the entity in database

Prisma information

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

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

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

model ArweaveTx {
  id           String @id @default(uuid())
  txId         String
  txCommitment String
  ID           ID?
}

model ID {
  id          String    @id
  identifier  String
  provider    String
  default     Json
  others      Json[]
  arweaveTxId String
  arweaveTx   ArweaveTx @relation(fields: [arweaveTxId], references: [id])

  @@unique([arweaveTxId])
}

// Add your code using Prisma Client

export const storeId = async (id: Prisma.IDCreateInput) => {
	console.log(id)
	const data = await prisma.iD.create({
		data: id
	})

	return data
}

Solved this issue, was because of my database name, apparently it can't be ID

[janpio]

That sounds like a bug then.

Can you confirm again, with a database name ID in PostgreSQL things failed, but when you changed it to something else it worked?

[sk1122]

Yes, it failed with database name ID and not when I changed it to ObjId

[janpio]

I just realized: I think with "database name" you mean the name of the table in the database, which influences the name of the model in Prisma Schema?

[sk1122]

oh, my bad, yes i was referring to table name, sorry, it just slept out of my mind

Ran into the same error on Prisma v4.6.1; MacOS

{
  id: 'id',
  identifier: 'identifier',
  provider: 'provider',
  default: '',
  arweaveTx: {}
}
TypeError: outputType.fields is not iterable

and can confirm that the error disappears when renaming it to not ID
