[JoshuvaGeorge03]

Bug Report

I got an type error, when I try to do post message using

webkit.messageHandlers.cordova_iab.postMessage and the error was Type error: webkit is undefined and not an object. This only occurs in ios and not in android.

Problem

I can't able to send data back to my ionic/capacitor application.
After investigating, I have found out that this issue only present in cordova-plugin-inappbrowser v3.2.0... And this version not rise any issue with android, but cause issues with ios as I mentioned above.

So, kindly fix this issue.

@JoshuvaGeorge03 you appear to be using this plugin in a Capacitor project not a Cordova project which I would suspect is the cause of your project since the plugin code is designed to work in the Cordova runtime environment.

if that is the reason, then it should not work in my android project which is also capacitor project. and In ios also, cordova-plugin-inappbrowser v3.1.0 works.

Only cordova-plugin-inappbrowser v3.2.0 throws error in runtime when doing postmessage

I am hitting this issue in a Cordova project, built with PhoneGap Build. On iOS you do get an error saying that webkit is not defined when using the additional cordova-plugin-wkwebview-engine plugin for display of web content within my iOS app.

This same routine works in Android successfully using the standard InAppBrowser.

Both platforms are using the 3.2.0 version of the InAppBrowser.

Having the same issue on iOS. After reverting to 3.1.0, this works fine.
