Worker throwing unhandled exceptions (last 24h)

What it is

A Worker is throwing unhandled exceptions.

Why it matters

An unhandled exception returns an error to the user with no useful response. Because Workers sit at the edge, this often affects requests before they reach your application, so your origin metrics look healthy throughout.

How to fix it

Wrap the handler in try/catch, return a deliberate error response, and report the exception. Then fix the underlying cause — unhandled exceptions in Workers are usually an unchecked binding or a malformed request assumption.
