NEURLFilterManager Error 2 in macOS - How to Validate Configuration Parameters for setConfiguration or saveToPreferences

I'm currently testing URLFilter for use in a macOS product. After calling loadFromPreferences, I set the following configuration parameters:

pirServerURL = URL(string: "http://localhost:8080")! pirAuthenticationToken = "AAAA" controlProviderBundleIdentifier = "{extension app bundle identifier}"

However, when I call saveToPreferences, I get an Invalid Configuration error. Is there a way to determine which parameter is invalid or incorrectly set?

Also, I would appreciate any macOS-specific examples of using NEURLFilterManager, as most of the documentation I’ve found seems to focus on iOS.

Thank you.
