Let's confirm if this is new or if it already exists in 7.14 -- if it isn't new, let's wait on fixing until we get Angular removed.

Was there a kibana log error as part of the 502?

[neptunian]

This looks like it was introduced in 7.14.0 as I was not able to reproduce it in 7.13.3. I'll see if I can get a fix in before the last BC.

I saw this when I ran it today though I don't recall seeing the aggregations type error previously

I believe this is where it fails https://github.com/elastic/kibana/blob/master/x-pack/plugins/monitoring/server/lib/details/get_series.ts#L193. Using the docker-monitoring-cluster it worked in 7.13.3 snapshot and not 7.14.0

@neptunian @jasonrhodes I created a PR with a fix.
I've never seen the socket hangup error, in the toast UI I got directly the illegal_argument_exception 🤷‍♀️

Do we want it to be in the last 7.14 BC? It is scheduled for today, so not sure if we will have time to include the fix.
