Cannot initialize Prisma client with custom path, shows error in dmmf/utils.js

INTRODUCTION

Everything was working in "nexus-plugin-prisma": "0.16.1" and problem appeared in all next versions.

OS: 18.04.5 LTS (Bionic Beaver)" NPM: 6.14.8 NODE: v12.18.3

COMMENTS

I tried to debug that faulty file - node_modules/nexus-plugin-prisma/dist/schema/dmmf/utils.js by checking whats in packagePath. I think it holds wrong path to Prisma client. It is @prisma/client even I am using custom path, which is outside node_modules.

@lauriskuznecovs I had the same problem. For me was a conflict between my @prisma/client dependency with the nexus-plugin-prisma dependency.

I was using in my project:

"@prisma/cli": "2.7.1"
"@prisma/client": "2.7.1"

and nexus-plugin-prisma was using:

"@prisma/cli": "2.7.0"
"@prisma/client": "2.7.0"

I updated my package.json to use 2.7.0 and got it working.

A possible solution for you

I see that you are using:

"@nexus/schema": "^0.15.0"
"nexus-plugin-prisma": "^0.18.2"

try to change your nexus-plugin-prisma to 0.19.0. I'm using this configuration and it's working.

It did not helped. I got same error. Do you also have custom path for Prisma client?

If tried to debug file in which as an error:

/node_modules/nexus-plugin-prisma/dist/schema/dmmf/utils.js

exports.getPrismaClientDmmf = (packagePath) => { console.log(packagePath) // Returns "@prisma/client"
    let dmmf = undefined;
    try { console.log(require(packagePath).dmmf)  // Returns "undefined"
        dmmf = require(packagePath).dmmf;
    }
    catch (error) {
        throw new Error(`Failed to import prisma client package at ${packagePath}. The following error occured while trying:
        ${error.stack}`);
    }
    if (!dmmf) {
        throw new Error(`\
You most likely forgot to initialize the Prisma Client. Please run \`prisma generate\` and try to run it again.
If that does not solve your problem, please open an issue.`);
    }
    return dmmf;
};

@lauriskuznecovs I'm not using a custom path, just the normal import:

const { PrismaClient } = require('@prisma/client');

And the 'nexus-plugin-prisma' is handling the '@prisma/client' dependency for me. I don't have it in my package.json now.

[lauriskuznecovs]

As I mentioned above I am using custom path for client.

generator client {
  provider      = "prisma-client-js"
  output        = "./src/generated/client" <------------ here
  binaryTargets = ["native", "linux-musl"]
}

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

///..... HERE are some models

That is described in Prisma docs, so there should not be a problem with custom path. https://www.prisma.io/docs/reference/tools-and-interfaces/prisma-client/generating-prisma-client#specifying-a-custom-output-path

[betofigueiredo]

It shouldn't be a problem, but maybe nexus is handling some prisma-client config as well and it's conflicting.

In my file the generator is only setting the provider:

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

[fullStackDataSolutions]

I'm using a custom location for storing the client. The client works but when I try to add it to nexus I get the same error.

Here's the versions I'm using:

"nexus-plugin-prisma": "^0.22.0" "@prisma/cli": "^2.9.0" "@prisma/client": "^2.9.0"

I suspect the error is somewhere in this code:

plugins: [
        nexusSchemaPrisma()
    ],
    typegenAutoConfig: {
        contextType: 'Context.Context',
        sources: [
            {
                source: require.resolve(
                    '../generated/prisma/saved_search/client'
                ),
                alias: 'savedSearch'
            },
            {
                source: require.resolve('../utils/types'),
                alias: 'Context'
            }
        ]
    }

[lauriskuznecovs]

I can confirm this is still an issue with current latest versions.

"dependencies": {
    "@prisma/client": "^2.13.1",
    "apollo-server": "^2.17.0",
    "dotenv-flow": "^3.2.0",
    "graphql": "^15.4.0",
    "nexus": "^1.0.0",
    "nexus-plugin-prisma": "^0.27.0"
  },

Hello @lauriskuznecovs,

This confused me also. The client path should be set in the nexusPrisma config inputs.prismaClient property. https://nexusjs.org/docs/plugins/prisma/overview#configuration

And reference the type definition file in the sourceTypes.

export const PRISMA_PATH = path.resolve(__dirname, '../../generated/prisma2');

const nexusPrismaConfig: NexusPrismaOptions = {
  inputs: { prismaClient: PRISMA_PATH }
};

export const schema = makeSchema({
  types: types,
  plugins: [nexusPrisma(nexusPrismaConfig)],
  ...
  sourceTypes: {
    modules: [
      {
        module: `${PRISMA_PATH}/index.d.ts`,
        alias: 'prisma'
      }
    ]
  }
});

I'm also having this issue when trying to deploy my app to Google App Engine. Everything works locally, but the remote deploy fails (the GAE node install mechanism is a bit obscure tho). I'm not using any custom path.

I'm trying to use Prisma in a monorepo with 2 services. The prisma folder is a symlink to ../shared/prisma.
