Cannot read property 'find' of undefined (UnhandledPromiseRejectionWarning)

I'm building an app in Ionic using Angular/Firebase.

I want to test the app on my android device, which, previously has worked perfectly. However, recently I've not been able to run it as I get an error.

$ ionic cordova run android --device --prod

Which then results in an error:

I'm not sure why this is happening. I tried removing my node_modules folder and then doing npm install, but that didn't fix it. I think it could possibly be an android issue? As I'm still able to build on iOS...

Any ideas? Thank you!!
