I kinda suspect all the windows CI issues are a result of the paths not being normalized which might (based on where things fail) to be a preexisting issue. Unfortunately, I don't have a windows machine I can test on so this could be a pain for me to track down.

I think the proper solution to the windows breakage is to wrap the values paths as rlocationpath(values, ctx.workspace_name) but that seems to break think on Linux where I can test them so I'm wondering is the rlocationpath is incorrect when the file is a local source file. (I've had some fun in a different project fighting with all the permutations and how they get munged.)

@abrisco Do you have direct access to a Windows environment? Any way I can talk you into taking a look at this?

I do not have a windows environment. All windows development has been done with github actions and prayer. Though I don't think the issue is too mysterious

This seems like parseHelmOutput might need to sanitize windows paths to unix?

The missing path isn't a template file but rather template_values.yaml which shouldn't show up in the helm output. I think the second error cascades from the first, likely due to the templated config ending up empty (which kind of suggests that the runner isn't detecting that helm failed). And from what I can tell, helm handles paths internally as always using / (I pushed several commits that tried variations on path munging but they didn't un-break anything).

PTAL.

I've duplicated the path munging in runner.go from the chart path to the values paths (and re-plumbed things so that the values paths aren't directly forwarded to helm).

Thank you!
