I'm using Helm 3 and microk8s. When I try a dry run:

microk8s.helm install <...> --dry-run --debug

I see errors like

Error: YAML parse error on ./templates/deployment.yaml: error converting YAML to JSON: yaml: mapping values are not allowed in this context
helm.go:76: [debug] error converting YAML to JSON: yaml: mapping values are not allowed in this context

I found several questions with a similar error, but the answer is usually just asking for read a chart code. I have a large chart and need to debug this error on my own. And guessing which line it complains about doesn't seem meaningful.

Is there a way to know what exactly is wrong in the config?
