When running /usr/libexec/ApplicationFirewall/socketfilterfw --add <path> the error message: "The file path you specified is invalid" is returned. This as worked on all the previous macOS versions. Has anyone run into this? Thank you.

I've been successful with creating a Network Extension application and an Endpoint Security Extension application, but I would like for there to be only one application that the user needs to install. I first started by adding the "System Extension" entitlement to my Network Extension app and that caused the app to stop functioning. Thank you for any help!
