Cordova prepares ios 'undefined' team

I am trying to run cordova prepare ios

on command line so I can then use Xcode to build my ios app. It just returns 'undefined'. It usually has no console output, but the application is prepared correctly. There are several developers on this project and I recently had to fix a few merge conflicts in a file Images.xcassets/launch.launchimage/Contents.json

, but beyond that I haven't touched on the cordova config settings. Any help would be much appreciated.

This is the output when I run it with the verbose flag. I would add more code, but I honestly don't know where to start looking for the error.

$ cordova prepare ios --verbose
