From a bug report on the AAB parsing lib we use.

The bundle manifest is "obfuscated" by using the Android resource IDs for XML attributes, rather than the plaintext attribute names, e.g.:

<manifest xmlns:android="http://schemas.android.com/apk/res/android" _0x0101021c_="16.5.0.86766a0184" _0x01010572_="29" _0x01010573_="10" android:installLocation="0" android:versionCode="160500001" package="x.y.z" platformBuildVersionCode="29" platformBuildVersionName="10">

    <uses-sdk _0x0101020c_="23" _0x01010270_="29"/>

    <uses-permission _0x01010003_="android.permission.INTERNET"/>
    <uses-permission _0x01010003_="android.permission.ACCESS_NETWORK_STATE"/>
....

This means that the bundle parser returns empty or default value for properties like `versionCode`. The application ID should still be parseable, and uploads should presumably work, but I imagine we show the wrong information in the console log for `versionCode` (i.e. `0`), which can also have knock-on effects for other plugin features.

We should try and fix the parser, and integrate a new release into this plugin.
