@DouglasHennrich Is it happening for any barcode scanned or any special barcode?

[DouglasHennrich]

Any kind of code, but I'm testing on QR Code and FORMAT_EAN_13

[vijaysingh-axway]

@DouglasHennrich I have tried app given in example of barcode. It is giving proper result. I try to run your code but is giving error in building. Can you please share complete code which I can run. It is better if you can share classic app for this code. Thanks!

[DouglasHennrich]

I don't know if it's related but I open a new window just to do this scan logic and I get the crash when I call: $.trigger('scanned', { barcode: event.result, callback: () => $.getView().close(), })
