The CI just errored out with no explanation.

Like nothing...

Just code 127 on bash...

I think the CI hates me

Add "set -x" to print every executed line. It's not a debugger, but better than nothing.

I am sure 127 here has a deeper meaning than 42

The CI hates everyone, so atleast it's not discriminating against anybody.

127 is an special errorcode. It means:
COMMAND NOT FOUND

Sometimes my tools just refuse to work. No real reasons, and digging through the actual errors is an endless rabbit hole.

Nothing to do but restart everything or sometimes restart yourself and try again the next day. 🤷🏻‍♀️
