Hi there guys, I've been trying to get rid of this error for days. I am using Next JS, and I am not been able to configure my Prisma client. It doesn't matter what I do or try that I always end with this error. This is the code I am using:

import { PrismaClient } from '@prisma/client';

let prisma: PrismaClient;

if (process.env.NODE_ENV === 'production') {
    prisma = new PrismaClient();
} else {
    if (!(global as any).prisma) {
        (global as any).prisma = new PrismaClient();
    }
    prisma = (global as any).prisma;
}

export default prisma;

I've have also tried this:

import { PrismaClient } from '@prisma/client';

declare global {
    // allow global `var` declarations
    // eslint-disable-next-line no-var
    var prisma: PrismaClient | undefined;
}

export const prisma =
    global.prisma ||
    new PrismaClient({
        log: ['query'],
    });

if (process.env.NODE_ENV !== 'production') global.prisma = prisma;

This is the error that I am getting:

Where is this file in your code? Prisma needs to be initialized and leveraged in your server side code. If you import this file at all in your TSX/JSX files that is going to cause this error. In our application we keep this in

lib/server/prisma.ts

and have lint rules to prevent TSX/JSX files from importing anything under

/lib/server

Hi @Javier Sebastián Fernández 👋 Just like Pranav pointed out, importing the server side code in any of your client file will result in this error. You can also enable

DEBUG

mode by following the steps here to get additinal logging output

👋 hey @Javier Sebastián Fernández, did you have a chance to try the solutions above? Let us know if this helped!
