Solution
Based on the knowledge sources, I can see that you're encountering a PrismaClientInitializationError when trying to use Prisma Client to fetch data. This is a common issue that can occur for several reasons.

The main issue appears to be that you're trying to use Prisma Client directly in the frontend/browser environment, which is not supported. Prisma Client is designed to run in a Node.js environment only and cannot be used directly in browser code.

As mentioned in one of the discussions:

To solve this issue, you should:

  1. Only use Prisma Client on the server side, not in client components
  2. In Next.js, you should use Prisma in:
    • API routes
    • Server components
    • getServerSideProps or getStaticProps functions
If you're using Next.js, create an API route that fetches the data using PrismaClient on the server side, then call that API from your frontend components.

Another common solution is to initialize Prisma Client only once and only on the server:

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

declare global {
  namespace NodeJS {
    interface Global {
      prisma: PrismaClient;
    }
  }
}

let prisma: PrismaClient;

if (typeof window === "undefined") {
  if (process.env.NODE_ENV === "production") {
    prisma = new PrismaClient();
  } else {
    if (!global.prisma) {
      global.prisma = new PrismaClient();
    }

    prisma = global.prisma;
  }
}

export default prisma;


This pattern ensures that Prisma Client is only initialized on the server side and prevents the "PrismaClient is unable to run in this browser environment" error.
