NEXTJS - Production Build Error - panicked at 'the global thread pool has not been initialized

Question

I am using Heroku to host my app and when I run git push heroku main it gives me the following error: panicked at 'the global thread pool has not been initialized.: threadpool builderror { kind: ioerror(error { kind: unsupported, message: "operation not supported on this platform" }) }'

How should I solv this issue? Language = NextJS hosting = Heroku

And here is my package.json, full error log & next.config.js

next.config.js

/** @type {import('next').NextConfig} */
const nextConfig = {
  reactStrictMode: true,
  swcMinify: true,
};

module.exports = nextConfig;

I tried using latest node version and old node@16 version but none of them worked.

Answer 1

It seems like an issue with the swcMinify option in the nextConfig, try setting it to false.

const nextConfig = {
  reactStrictMode: true,
  swcMinify: false,
};
