How to inspect Deno's rare uncaught rejections?

I'm encountering an AbortError with Deno.serve, but it's difficult to report the issue since I can't reliably reproduce it. Based on the stack trace, I can't seem to catch the error, as there’s no clear interception point.

How can I investigate and debug this?

TamperDAV is running without any form of authentication. It's strongly recommended to configure username and password!
