Accessing reverse dependencies for serde returns an HTTP 500 and redirects to /

[alex]

Current Behavior

When I go to https://crates.io/crates/serde -> press Dependents an HTTP 500 is returned (bug #1) and then the whole page redirects to / (bug #2)

Expected Behavior

a) Obviously the 500 is a bug
b) If a 500 occurs, we should stay on the current serde page, not redirect to /

Steps To Reproduce

No response

Environment

No response

Anything else?

I think the 500 is a timeout. It seems to happen at the 10 second mark each time. For what it's worth, I got the page to load after a few refreshes.

On a local instance of crates.io it takes about 2 seconds but loads fine. It makes sense that this would take longer in production due to the load on the database.

Perhaps for more popular crates the reverse dependency index needs to be generated in a background job rather than on demand.

Fixed the redirect on error. The core issue of reverse dependencies taking a long time to load or not loading at all is still present.
