502 Bad Gateway: Registered endpoint failed to handle the request
Cause
The problem is that the Schedule Status page is poorly optimized. If a tenant has a lot of schedulable jobs, it will take a long time for a backend request to fetch the jobs to display. Browsers have a timeout of 5 minutes for backend requests so if the amount of work to fetch the jobs exceeds 5 minutes then you get what you saw on your tenant.
Resolution
Optimized some steps of the backend request so that it's less likely to exceed the 5 minute threshold (notice that when you had the issue, the loading screen would usually fail after 5 minutes, now results return within ~2.5 minutes). This change has been patched to the next QRC upgrade QRC 2 2025.
