To prevent querying large dataset with an “empty” report you can enable this feature flag.
Navigate to [domain]/secure/admin/SiteDarkFeatures!default.jspa
On this page, add the “everit.jttp.at.least.one.user” key
if it is added and enabled:
on the “Reporting” page, at least one user or group (at least with one member) must be selected to generate a report
Warning message won’t appear on Chart Report, but the same restriction applies to it
If you want to allow it again, you just have to click on the disabled button on this page. No need to restart and stop the addon.
