I once got a nil pointer exception when I updated a helm chart. I wondered why the hell am I getting a nil pointer exception for updating a YAML file. After some investigation I found an issue on GitHub where the maintainers said the Go team says this is an intended behavior for some case in Go templates.

Wasn't fun.

That isn't a typical nill/null exception, like in JavaScript, ruby, and python. That's in a language where a lot of values are non-nullable, and some of the ones that are have zero-values that can be used without getting a nil pointer exception. https://go.dev/tour/moretypes/12

So, there's a good chance was an error that was really unexpected and it's better to show the error than to risk producing bad output.
