I'm using Elastic Stack 6.8.12 and running into following issue:
XXXX | [2020-10-05T00:22:46,990][WARN ][o.e.i.s.IndexShard ] [XXXXX]  onPreFetchPhase listener [org.elasticsearch.xpack.security.authz.SecuritySearchOperationListener@50e79b24] failed
XXXX | org.elasticsearch.ElasticsearchSecurityException:  expected scroll indices access control
I cut line as it's extremely long (~5000 characters long).
I get numerous lines, one after another to the point where I run out of space (due to excessive logs).
