for the info my cluster is on version 7.17.4 and it's based on 3 nodes that are all master eligible and data nodes.
I keep getting this warning on my master node logs non-stop, [2023-06-13T15:44:07,212][WARN ][o.e.x.s.a.ApiKeyAuthenticator] [node2] Authentication using apikey failed - unable to find apikey with id <id>
To troubleshoot i used GET /_security/api_key?id=<id> API and effectively there were no key with the specified id.
What could happened to make this id disapear and what is the proper fix to this warnings ?
Thank you @Yang_Wang, I tried to take this approach but I wasn't able to find out the service using this apikey. is there any way to find out ?
The only infromation I'm getting is this warning and it's happening very repeatedly (every 5 seconds or so).
I would like to know at least all process that use apikey by default, maybe it would help find an anomaly with one of them or maybe when listing apikeys I find someone missing.
