I am also experiencing this error as of recently. Any help would be appreciated

In your config.xml, after running the ionic cordova run ios command, you will see there is an entry in there along the lines of <allow-navigation href="http://:8100" />. It is trying to parse out the IP address from this line but that is obviously returning null.

To solve, I removed this line and re-ran it. Weirdly it took a couple of runs before it stopped auto-generating this in my config.xml
