I see that users are getting the following error in my app. The problem is that the stacktrace doesn't lead to the point of origin in my app. Although I highly suspect it is a certain custom text field (Code below) that causes the error. Since I cannot reproduce the error on my own, I wonder if someone has some tips on how to investigate such issues in general or tips on this specific crash.
Code causing issues (likely, not certain)
