@TamimiGitHub can you take a quick look at the preview failing? Per the AI does this fit with the netlify issues you troubleshot recently?

The failure occurred during the npm install step with the error: npm ERR! Cannot read property 'fs' of undefined. This error is common when using an outdated Node.js version with newer npm dependencies.

Solution:
Update the Node.js version from 12.x to at least 16.x in your workflow. In .github/workflows/netlify.yml, replace:

- name: Install node 12.x
  uses: actions/setup-node@v1
  with:
    node-version: 12.16.2

with:

- name: Install Node.js 16.x
  uses: actions/setup-node@v3
  with:
    node-version: 16.x

This should resolve compatibility issues with npm packages and fix the failing job.
