Cannot add platform android in a Ionic V3 application due to unspecified incorrect JSON file

Hello all!

I am trying to re-add android platform within an Ionic-3 application and I cannot figure out why it fails.

ionic cordova platform add android --debug

× Running command - failed!
[ERROR] Exception: Using cordova-fetch for cordova-android@~6.2.2

    Adding android project...
    Creating Cordova project for the Android platform:
            Path: platforms\android
            Package: ...
            Name: ...
            Activity: MainActivity
            Android target: android-25
    Subproject Path: CordovaLib
    Android project created with cordova-android@6.2.3
    **Error: Unexpected token q in JSON at position 379**

(I received the same output running with --verbose parameter)

ionic info:

cli packages: (F:\Alex\GoogleDrive\Projects\GitHub\NewsAggregatorMobile\node_modules)

@ionic/cli-utils  : 1.9.2
ionic (Ionic CLI) : 3.9.2

global packages:

Cordova CLI : 7.0.1

local packages:

@ionic/app-scripts : 2.1.3
Cordova Platforms  : android 6.2.3
Ionic Framework    : ionic-angular 3.6.0

System:

Android SDK Tools : 26.1.1
Node              : v6.10.2
npm               : 3.10.10
OS                : Windows 10

Clearly, there is a messed-up JSON file, but I cannot figure which one and the error is not helpful at all.

Any way to find out which file it is about?

Thanks.

Found it: \plugins\fetch.json

It would be great to have more specific errors, though.
