Trying to apply a new MNG via the this module, but getting Invalid validation error message, seems like the error message is missing punctuation.

Reproduction Code [Required]
Steps to reproduce the behavior:
were not even using the argocd addon - but for some reason when trying to install the module it still depends on the addon...
