To me, that makes it sound like you’re writing too much and too complex yaml files manually, and/or that you don’t have good enough CI to catch invalid configurations. Unless, of course, you have very few prod failures overall, and the few that happen are due to yaml indentation, which I still think is a bit weird, since an invalid config caused by incorrect indentation should ideally be caught at compile time (if you’re generating code from the yaml) or by some linter or something (if you’re using it for config).
