Hey!
We've recently migrated our Jira Data Center instance to a new instance of Data Center and we've had some reports from users when they export any number of issues using CSV (All Fields) it generates a blank CSV.
I have done some testing of my own and found the following
CSV (All Fields) - This generated a blank CSV file even with a query of 316 results.
CSV (Current Fields) - This generated the CSV as intended with the same query of 316 results.
Our `jira.search.views.default.max` is set to 10000 and I am unable to find any solution so far.
