Unable to build project, Cannot read properties of null (reading 'useContext') about next.js HOT 4 OPEN

Might be related with #57277, which was closed due to no re-pro link.

from next.js.

Suddenly I started catching this error too

Example pipeline - https://gitlab.com/shortlink-org/shortlink/-/jobs/6368837674
Repository: https://github.com/shortlink-org/shortlink/tree/main/boundaries/ui/nx-monorepo/packages/next

I've tried leaving 1 blank page, tried different versions of nx/next/etc, checked that the peer dependencies are correct, deleted the cache, and upgraded the NodeJS version to 21.7 - but nothing worked.

from next.js.

I am having the same issue here

from next.js.

Looked at the repo https://github.com/zlace/next-build-error.
I added previous externals in the webpack config. Change next.config.mjs to this

/** @type {import('next').NextConfig} */
const nextConfig = {
  webpack: (config) => {
    return {
      ...config,
      externals: [...config.externals, "pino-pretty", "encoding"],
    };
  },
};

export default nextConfig;
