Simple "cordova plugin add" not working

[R-obert]

Documentation says in order to add the plugin I should do the following:

$ cordova plugin add cordova-plugin-fcm
Installing "cordova-plugin-fcm" for android
Subproject Path: CordovaLib
Subproject Path: app

		Cordova FCM plugin v2.1.2 installed
		For more details visit https://github.com/fechanique/cordova-plugin-fcm
	
Adding cordova-plugin-fcm to package.json
The "chunk" argument must be of type string or an instance of Buffer. Received an instance of Error

This breaks cordova build android, the only output it shows is that "chunk" argument message.

Hi, yes there is a fix for this. It is just a couple of lines of code.

See #501

I have forked and updated the problematic file. Feel free to use this one:
https://github.com/mike-nelson/cordova-plugin-fcm.git

cordova plugin add https://github.com/mike-nelson/cordova-plugin-fcm.git

However, this didn't get me far, and I got the next error:
This project uses AndroidX dependencies, but the 'android.useAndroidX' property is not enabled

Which can be fixed using this:
cordova plugin add cordova-plugin-androidx-adapter
