Server.edge not defined Error on nextJS SSR functions cause site to return 500 Errors

Hi @frederikfink this isn’t necessary and won’t help. Also this does not need to be done on our end.

Can confirm that applying the monkey patch above does work for me (next 13.4.3)

Where do you put this code?

In theory, anywhere before next-runtime bundling functions. But safely, I prefer to patch this code before running next build or any next cli.

This is how I did it:

  1. Create a prebuild script at prebuild.js in the route of your project. This is the code you want:
console.log("********* PREBUILDING");
const path = require("node:path");
const fs = require("fs");
const baseDir = process.cwd();

const prebuildScripts = async () => {
  const file = path.join(

  const content = await fs.promises.readFile(file, "utf-8");
  await fs.promises.writeFile(
      "if (process.env.__NEXT_PRIVATE_PREBUNDLED_REACT) {",
      "if (true) {"


  1. Update package.json to include a prebuild step:
  "scripts": {
    "dev": "next dev",
    "prebuild": "node prebuild.js",
    "build": "next build",
    "start": "next start",
    "lint": "next lint"

Thanks for sharing this with the community!

Yup this was the fix right here , i tried all other solutions from different posts but none of them worked
