This means we don't report up a useful error about what caused this. Should this function return a useful error?

I'm not sure it's possible to tell if this is actually an error since this runs during preview and Outputs may not yet be fully resolved. I suspect that it might lead to erroneous warnings.

This particular case was a bit odd because the outdented YAML still parsed cleanly, but changed the semantics of the configuration. This change fixes the panic, and now correctly shows a replacement in the preview. This should be sufficient for a user to notice that something is going wrong if they weren't expecting a change.

Looks like it. Good catch.
