   # Bug Report
   
   ## Problem
   Ok question may sound weird.
   
   I have 2 pages in my ionic 5 app.
   page A has a login screen, call its .service.ts file as a.service.ts
   page B has the Camera Preview plugin installed
   a.service.ts has a method to pass InAppBrowser instance to page B from page A. ( so I can add hook of postMessage)
   When inappbrowser instance is passed successfully to a.service.ts from A and to B as well.
   
   Looks like below 
   
   inside a.service.ts
   
       setIABPosstMessageHook(iab) {
          this.iabInstance = iab; // set iab passed from page A here
          this.router.navigateByUrl('camera-rdc'); // navigated to page success
          this.cameraRdcController.getIABFromSender(this.iabInstance); // check below for method
       }
   
   inside B (camera controller)
   
       getIABFromSender(iabInstance) {
       iabInstance.on('message').subscribe((callbackData) => {
         iabInstance.hide(); // hidie inappbrowser works
         this.iab = iabInstance // iab set successfully to global variable this.iab
         this.cameraTriggeredInIAB(callbackData.data.cameraSide); //starts camera
       });
     }
   
   now on camera page, I have a close button which calls below method - 
   
   
         exitCameraView() {
           this.cameraPreview.stopCamera().then(() => { //stop cammera
             this.screenOrientation.unlock(); // unlock landscape orientation
             this.iab.show(); // ERROR COMES HERE AS show  on undefined!!!! how?
           });
         }
   
   in debug mode, I see that its there in 'this' but after I click close button, somehow this iab is gone from this!! I can't seem to find how does this object got vanished.
   
   because of that, my IAB is not showing up again. Help, please. I haven't faced any such issue in the angular or ionic side till today, but now I don't have any clue. Thanks.
   
   ### What is expected to happen?
   
   show should work, but iab object is gone

   error as show on undefined
