Hi @shekharsanatan92, thanks for filing this! I think this is a duplicate of #37271 and should be fixed in the upcoming v1.13 release.

If it is the same issue, there is likely an invalid reference somewhere in your configuration within a try and can function call and you can unblock yourself by finding and removing that reference.

Thanks again!

Thanks @liamcervante , reverting my helm provider version from v3.x.x to v2.17.0 solved my problem for now.
