An error occurred while executing doInBackground() - Expo Barcode Scanner

Expo Development Tools

I am working on an ejected flow and am trying to use expo barcode scanner. However, every once in a while I get this error https://sentry.io/share/issue/f61de236a0cd49e0bf8f49cfc0c1fd6a/ The error didn’t occur even once before I added this library. Oh and the error also occurs even when the BarCodeScanner isn’t even on the active screen (or the user still hasn’t even yet navigated to the screen that embeds the BarCodeScanner.

@sheharyar566 did you fix this?

We are also experiencing issues. We cannot update apps on google play.

"expo-barcode-scanner": "11.1.2"
"expo": "43.0.0",

java.lang.RuntimeException: An error occurred while executing doInBackground()

The stack traces says Scan output cannot be null:
