running nexus v1.3.0, prisma v4.0.0 Error： Error: NEXUS__UNKNOWN__TYPE was already defined and imported as a type, check the docs for extending types

[recklyss]

Hey @reaink , can I please ask what's your current prisma version?

[reaink]

current version

    "prisma": "3.14.0",
    "nexus": "1.3.0",

update to prisma v4.x throw error NEXUS__UNKNOWN__TYPE

[kevscript]

I'm having the same error. Downgrading to v3.15.2 didn't fix it. Its still working on a previous project with this prisma version tho. Might be related to something else? It doesn't even generate the outputs for typegen and schema. @reaink any updates on your side?

[reaink]

@kevscript Yes, I hope Prisma 4.x can be supported, currently I'm still using prisma 3.x in current nexus version

[kostovaljubica7]

I'am having the same issue upgrading 3.15.2 -> 4.21 "nexus": "1.3.0",

Error: NEXUS__UNKNOWN__TYPE was already defined and imported as a type, check the docs for extending types

[Bjoernstjerne]

Fix this by edit builder.js 156 change "throw extendError(typeDef.name);" to "console.log(typeDef);" Fix your nexus API with the Errors you get now.

Three backend in production @ "nexus": "^1.3.0", with "prisma": "^4.1.1",

• What is the status of this issue?
• Has anyone solved this problem?

Having the same issue since updating to prisma v4

[sakhro]

Same issue

[Bjoernstjerne]

Have you tried my solution to remove the throw statement in the builder? Had the same issue after upgrading from 3.1x to 4.x I got some new errors by Nexus without the throw but this time with the type the error occured.

I don't think this is a prisma 4 specific error. I'm getting it any time I have more than 2 missing type definitions in my nexus schema:

To reproduce, create a field on an object of type: 'NotAType1', you'll get an error saying something about forgetting to export "NoteAType1"

Add a second field for 'NotAType2' and you'll get this error back instead and nothing about either NotAType1 or NotAType2: The below code will reproduce. Comment out the second line to see a helpful error message.

const ObjectA = objectType({
  name: 'NotImportant',
  definition(t) {
    t.string('fine');
    t.field('errorsWhenJustThis', { type: 'NotAType1' });
    t.field('unhelpfulWithThis', { type: 'NotAType2' });
  },
});

export const schema = makeSchema({
  types: [ObjectA],
  )}

[rgamm]

If you want, you can add detail to the error message by adding a log statement in node_modules/nexus/dist/builder.js:154

if (existingType) {
    if (existingType !== typeDef) {
        console.log(`Missing Types: ${Object.keys(this.missingTypes)}`); // <----
        throw extendError(typeDef.name);
    }
    return;
}

Might help you find the actual error

I'm getting this same error, I used the method here to identify what was causing the issue, and for me one of them was the DateTime type in Prisma.

[markymc]

@SysSU I'm also getting this error with DateTime type. Did you manage to fix it?

[SysSU]

@markymc it has been some time since I looked at this code but I think the following fixed it for me.

import { makeSchema } from 'nexus';

import {
  Json as jsonScalar,
  // Import DateTime scalar
  DateTime as dateTimeScalar,
} from 'nexus-prisma/scalars';

import * as types from './types';

export default makeSchema({
  // Add dateTimeScalar to types when calling makeSchema.
  types: { ...types, jsonScalar, dateTimeScalar },
});

[markymc]

@SysSU Thanks! That did it!
