Application Keys with dots (".") in the value cannot be edited/deleted

Issue

The system is allowing the creation of Application Keys containing a dot in the name (e.g. "key.test") but when we try to delete this same app key it is not allowed returning an error (see below). Either using the "Application Key Delete" API or through the UI Admin Portal it is not possible to delete the application key.
