I have an I/O function called from <http://Dispatchers.IO|Dispatchers.IO>, which throws a kotlinx.serialization.MissingFieldException error. The exception itself is irrelevant, I just want to know where the error window showing its details comes from. I don't know much about Swing or AWT, so is this done by Compose or is it a default behaviour of its underlying libraries? (screenshot cropped because I don't want to share all of it.)

It’s done by Compose. I’m not at the computer right now, so I can’t look up the exact API, but you can register an unhandled-exception handler.

[Alexander Maryanovsky]

It’s LocalWindowExceptionHandlerFactory

[Alexander Maryanovsky]

The default one is DefaultWindowExceptionHandlerFactory

Got it, thanks.
