Ingress does not treat / path as /*. However, everything works fine with path as /* but the controller has this above error ⬆️

@ns0092
There is PathType associated with each path. For "Prefix" type, it shouldn't contain any wild cards.
You may use "ImplementationSpecific" path type if you want to specify the path per ALB's syntax.
