Worker runtime error rate elevated (last 24h)

Part of the Workers, Pages & API tokens check · fix arrives as a guide

What it is

A Worker has shown an elevated runtime error rate over the last 24 hours.

Why it matters

Worker errors do not appear in your application logs, so an edge function failing on a share of requests can run for weeks unnoticed. Users see the failure; your monitoring does not.

How to fix it

Check the Worker's logs and metrics for the failing paths. Add a tail consumer or an error-reporting integration so Worker errors reach the same place as the rest of your alerts.
