After upgrading to 7.8.0 about 90 % of cvs reports empty (the corresponding saved search is not!).
Can't find any corresponding error messages in the kibana log.
The only one suspect is absence of .reporting-%date% indexes (don't really know what do the indexes for).
Also big (more than thousands of documents) reports often fail (
"Unable to generate report Max attempts reached (3)"
xpack.reporting.csv.maxSizeBytes: 104857600 #xpack.reporting.queue.timeout: 120000 = 20min xpack.reporting.queue.timeout: 120000 )
Any ideas / thoughts?
