global_search_apdex SLI graphs in Grafana are broken

With the newly created global_search_apdex SLI, some graphs were automatically created on the Global Search: group error budget detail page, however they don't always seem to load (every so often they do). The graphs can be found under 🔬 SLI Detail: global_search

Running a single graph query (menu > explore) often results in the following error:

Query error
<html><head> <meta http-equiv="content-type" content="text/html;charset=utf-8"> <title>502 Server Error</title> </head> <body text=#000000 bgcolor=#ffffff> <h1>Error: Server Error</h1> <h2>The server encountered a temporary error and could not complete your request.<p>Please try again in 30 seconds.</h2> <h2></h2> </body></html> 

Checking the data in a different environment like gstg will load data in the graphs (if it says no data, try performing a couple of searches in Staging first)

On the web/api service graphs the same graphs are also available (but scoped to web/api respectively, so more filtered down), and the graphs seem to load more consistently there: https://dashboards.gitlab.net/d/web-main/web-overview?from=now-30m&to=now&orgId=1
