This looks to be a real issue happening in cloud, but I would need the Kibana App team to confirm.

Here is the response of the 500 (Internal Error) - it is happening on filebeat and metricbeat selection.

{"statusCode":500,"error":"Internal Server Error","message":"[too_complex_to_determinize_exception] too_complex_to_determinize_exception: Determinizing automaton with 189419 states and 192471 transitions would result in more than 10000 states."}

Looks like this was a real issue fixed by PR: https://github.com/elastic/kibana/pull/55745 -- I will rerun on next BC to test out the fix.

[wylieconlon]

This test is in 7.6 branch, but probably didn't make it into the 7.6 snapshot build for cloud- this shows that the test is correctly catching the bug.

[timroes]

@liza-mae Canyou confirm somehow, that this is the problem, so we could close this?

[liza-mae]

@timroes I need to wait for BC3 to be available, it is not yet. They are building it as of now but then cloud team still needs to post it on staging, I will close it when I confirm the fix.

[liza-mae]

Confirmed this is fixed in BC4 yay! :) Thanks @wylieconlon for adding this test, it shows great value when we can catch real issues.
