Can you please tell us more about the app workflow and describe the conditions the lead to app crash?

It would be great if you can provide some sample code and some data we could try.

Hi Preeti. This error is taken completely out of context as it comes from Sentry monitoring and the given report doesn't really point to what area in the app the error pertains to. If we're lucky it will one day happen while the developers are running the app. Until then I can't provide you with further details. Thanks
