---> db.ts of web applicaiotn

import { PrismaClient } from "@repo/database";

const globalForPrisma = global as unknown as { db: PrismaClient };

export const db = globalForPrisma.db || new PrismaClient();

if (process.env.NODE_ENV !== "production") globalForPrisma.db = db;

generator client {
  provider = "prisma-client-js"
  // Disable its causing issues with the esm based project of nodejs 
  // output = "../generated/prisma"
}

You can try this:

generator client {
  provider = "prisma-client"
  output = "../generated/prisma" 
}

And then modify the import base on output location like:

import { PrismaClient } from "@/generated/prisma/client";

If you use prisma-client-js you need to define engine: classic, and then import prisma client from @prisma/client package.

In the upcoming version, I think it will be default with no rust engine in prisma v7

Working Setup files
--> Next config.ts

import type { NextConfig } from "next";
import { PrismaPlugin } from "@prisma/nextjs-monorepo-workaround-plugin";

const nextConfig: NextConfig = {
  /* config options here */
  webpack: (config, { isServer }) => {
    if (isServer) {
      config.plugins = [...config.plugins, new PrismaPlugin()];
    }
    return config;
  },
};

export default nextConfig;

Prisma schema 
generator client {
  provider = "prisma-client-js"
  // Disable its causing issues with the esm based project of nodejs 
  // output = "../generated/prisma"
}

This solution to had worked for me from the prisma AI

Thanks sir @Shyam Verma
