UPGRADE FAILED: nil pointer evaluating interface

[0x2b3bfa0]

From #123 (comment)

The lint-test workflow may break unexpectedly when the pull request branch contains new values not present in the main branch. As per #123 (comment), we can wrap every level with parenteses to avoid the error, but values will still be null.

Example

Error: UPGRADE FAILED: template: studio/templates/raycluster-studio.yaml:1:14: executing "studio/templates/raycluster-studio.yaml" at <.Values.ray.enabled>: nil pointer evaluating interface {}.enabled
