Skaffold setValues is getting missing helm values

Question

Skaffold setValues is getting missing helm values.

Instead of setValues, when I save the relevant values in the values.yml file and use valuesFiles, there is no problem and the rendering is successful.

I guess setValues doesn't recognize nested arrays. Please review the example below.

Why the ingress.tls[0].hosts doesn't exist?

This was fixed recently via the PR here: https://github.com/GoogleContainerTools/skaffold/pull/8152

This is currently in skaffold in main and will be available in the v2.1.0 Skaffold release (to be released 12/7/2022) and onward
