Quick fix: 'Error: Process completed with exit code 1' in GitHub Actions with regex

In summary, I was running GitHub Actions and I had a regex expression using grep:

grep -Eo "\d+[.]\d+[.]\d+"

This was to retrieve a version number from a line. For example, 1.1.0. The solution worked locally, but it failed in my CI/CD.

Then, I found out this issue: Grep failing in GitHub Action, working locally and you can see from there the fix:

So that's what I did, and BOOM it worked!

grep -Eo "[0-9]+[.][0-9]+[.][0-9]+"

Just writing it out here so I remember how I fixed it in case I see the error again :D

Also here are some screenshots from my actual pipeline:
