runtime/uncaught-exception

This error happens when an exception, of some kind, was thrown and then not caught by your program’s code. The jank runtime caught the exception and then surfaced the stack trace, along with the exception message.

Mitigations

Inspect the stack trace to find where the exception was thrown and whether or not that was intended. If the exception was intended, add a try to your program so that you can catch the exception yourself.
