-/issues doesn't return a list of issues; returns "An error occurred while getting work item counts".

How To Reproduce

Visit gitlab.com/gitlab-org/gitlab/-/issues.

The Erroneous Consequence

An error occurred while getting work item counts.

I always see this. If one visits google.com/search?q=An+error+occurred+while+getting+work+item+counts.+GitLab, they'll see that it's been indexed across SAAS and non-SAAS instances, too.

Conducted Diagnosis

Before the error appears, I see:

11:48:13.986 XHRPOST
https://gitlab.com/api/graphql
NS_BINDING_ABORTED

During and afterward, I see:

1. 11:48:14.412 XHRPOST
   https://gitlab.com/api/graphql
   [HTTP/2 503  15758ms]

2. 11:48:14.413 XHRPOST
