Any help please

did you check the database table tabReports
select * from tabReports where name =‘Jasper Erpnext Report’

if it is exist delete it

Dear @MiM,

I tried that but i got an EMPTY SET as my return…

I had to delete, uninstall and remove the app then do a bench migrate before i could get it installed back but i am trying to connect erpnext to jasper server but it keeps telling me to install PYJNIUS which i have done. Any help please
