Custom Prisma Client is not working

[brandoncollins7]

I am using an nx mono repo and I have my prisma models dumping to a library. So I am trying to integrate this by using a custom prisma client:

`import {PrismaClient} from '@frnt/lending-api/models'

@Global() @Module({ imports: [ CustomPrismaModule.forRoot({ name: 'PrismaService', client: new PrismaClient() }),`

But it just seems like it is not working at all because when I run it is looking for the prisma client in node_modules?

`Error: Cannot find module '.prisma/client/index' Require stack:

• node_modules.pnpm@[email protected][email protected]\node_modules@prisma\client\index.js

Hi @brandoncollins7, how are you accessing the database are you using CustomPrismaService? Do you have a reproduction repository, which would be easier to help if i can reproduce it myself.

[marcjulian]

I cannot reproduce it atm. Please provide a reproduction repo.

Hi @marcjulian, I'm having the same issue but with a PNPM and Turborepo monorepo. I am using CustomPrismaService<PrismaClient> with my PrismaClient exported from the output.

I have tried both exporting the custom output to node_modules as specified on the documentation as well as on a folder inside my src directory, but it seems that nestjs-prisma is trying to import the default @prisma/client and it cannot find it (prisma generate creates the Prisma client on the specified custom output). I'm attaching the error:

generator client {
  provider = "prisma-client-js"
  output   = "../node_modules/@org/client"
}

app.module.ts

import { CustomPrismaModule } from 'nestjs-prisma';
import { PrismaClient } from '@org/client';

...
CustomPrismaModule.forRoot({
  name: 'PrismaService',
  client: new PrismaClient(),
  isGlobal: true,
}),

I can help providing a small repo to reproduce, but that will take a bit of time. Maybe this can help in the meantime? 😄

[marcjulian]

Thanks for the error logs. Looks like PrismaService, which is in the package is trying to access the default prisma client. I will add an example and see if I can reproduce the same error.

[marcjulian]

It looks like that this is caused because of the index.ts exporting all files from the library, even though PrismaService is not used it imports from @prisma/client.

I guess the import need to change e.g.

- import { CustomPrismaModule } from 'nestjs-prisma';
+ import { CustomPrismaModule } from 'nestjs-prisma/custom';

https://github.com/notiz-dev/nestjs-prisma/blob/a84e24d8f204e978fa1158c1d908a603df62b2fb/lib/index.ts#L1-L4

A current workaround would be to change the imports too

import { CustomPrismaModule } from 'nestjs-prisma/dist/custom';
import { CustomPrismaService } from 'nestjs-prisma/dist/custom';

[mvp-studio-repo]

Hi, thanks for the workaround, but it's seem we can't use the PrismaClientExceptionFilter with this (as it's also require prisma/client)

Do you think it will be possible in the near future to use all the feature with a custom client ? or is there also another workaround for this case ?

[Krr0ptioN]

I am facing the same issue, I managed to solve this issue with workaround (thanks to @marcjulian), although I am not sure whether this is a stable or temporary solution.

My stack:

• Nx, typescript
• Custom Prisma Client path

[mvp-studio-repo]

@Krr0ptioN Could you share / show how you did your workaround ?

[marcjulian]

@Valetek have you tried this workaround? https://github.com/notiz-dev/nestjs-prisma/issues/79#issuecomment-1768053972 I think @Krr0ptioN means that workaround.

[mvp-studio-repo]

HO yes this one, finally I used the setup for custom config (with prisma module) and everything is working fine, except that I used my own custom FilterException

I did tried this workaround but it's still fail when calling the prismaFilterException

[marcjulian]

Yes PrismaClientExceptionFilter does not currently work for custom location. I will have a look on a fix for that as well.

[Krr0ptioN]

@Valetek this workaround

[marcjulian]

I am facing the same issue, I managed to solve this issue with workaround (thanks to @marcjulian), although I am not sure whether this is a stable or temporary solution.

My stack:

• Nx, typescript
• Custom Prisma Client path

This is currently a temporary solution. When I have the time I would like to move all exports related to custom prisma service under nestjs-prisma/custom.
