Ended up needing to find where a defect was introduced. Tunrs out there is a command for that. git bisect to the rescue!

Bisect Steps

1. Start the Process.

git bisect start

2. Mark current commit as bad (error is present):

git bisect bad

3. Mark last known good commit (error NOT present):

git bisect good <commit_hash>

4. Git will check out a commit halfway between the good and bad commits. Test if the error is present:

• If the commit has the error, mark it as bad:

git bisect bad

• If the commit does not have the error, mark it as good:

git bisect good

5. Repeat step 4 until Git identifies the problematic commit.

6. End the bisect process:

git bisect reset

Truns out the rabbit hole goes super deep based on some documentation I found online.

Happy Coding ;-)
