Ingest Manager - unable to check permissions message seen on the screen -while logged in as elastic super user.

Kibana - BC7 - 7.9.0

I just spun BC7 - 7.9.0 and when I navigated to Ingest Manager I saw the following , although I was logged in as elastic super user.

logs in the console say

:5601/api/ingest_manager/check-permissions:1 Failed to load resource: net::ERR_EMPTY_RESPONSE
core.entry.js:84 Detected an unhandled Promise rejection.
TypeError: Failed to fetch

However I was not able to reproduce this again. Upon reload of the page, I saw that the page was rightly served, and got 200 response.

Refreshing the page with dev tools open, and looked for Network tab in Dev Tools:

Request URL: https://localhost:5601/app/ingestManager
Request Method: GET
Status Code: 200 OK
Remote Address: 127.0.0.1:5601
Referrer Policy: no-referrer-when-downgrade

Logs looked clean . Logging this intermittent bug.

Thanks Rashmi!

@jfsiii Can you investigate it, this look like a major issue?

@EricDavisX Did you run into that with the latest snapshots.

related to #71641

I wasn't able to reproduce this initially, but after working out steps to reproduce #75497 I was able to get a "no admin user" error like #71641

I also have a better idea how to simulate errors at different layers now. I'll add tests for this as a part of #66688

[EricDavisX]

sorry for late reply @ph no, I didn't see this - tho I hadn't been in the 'Stack Management' as often, unless I had a specific need

[jfsiii]

I haven't been able to reproduce this specific error. However, I believe our work in #77975 & #74409 will a) prevent the unhandled promise rejection b) give more details if it does occur again.

@ph I'm closing this but feel free to re-open

[ph]

sound good @jfsiii

Folks, I still see this problem with version 7.10 elasticsearch, kibana, (and logstash -- for completeness. ). All installed via homebrew.

This is the mystery log message from the log (whole log attached as kibana.log.1.zip )

...
{"type":"log","@timestamp":"2020-12-08T05:53:56Z","tags":["warning","environment"],"pid":98654,"message":"Detected an unhandled Promise rejection.\nError: Cannot delete files/directories outside the current working directory. Can be overridden with the `force` option."}

Attached are the config files from my last iteration.
