Since I was the one who helped you with the initial perl-ci.yml, I was a bit embarrassed that it didn't work straightaway for you on this project. Unfortunately, my weekend was swamped, so I didn't get a chance to fork your repo and run experiments until today... Sorry

No need to be sorry or embarrassed...
I wouldn't have got this far without you previously pointing me in the right direction. I'm very grateful for that.

I'm acutely aware that there is a huge amount that I don't know and thankful for every bit of enlightenment I get from others.

I don't have time and opportunity to always check these things in timely fashion so don't worry about delays.
