I use koolreport with laravel, and I build a pivot table.
The report is working fine when data exists in the selected period.
But if there is no data in selected period, seems a error message 'error' is throw out.
When debuging, I try to output the datastore('period') which I used for select, it is empty. I'm quite sure it should contain data.
I cannot find any error message in laravel log. Is there anyway to debug?
