Thank you for reply I'll ask for log from my co-worker next Monday

I'm using TIBCO Jaspersoft® Studio 6.20.0 I follow the tutorial to generate report https://community.jaspersoft.com/wiki/using-data-adapters-fill-reports-json-data-remote-url everything works fine in local I can run in my local servers my default data adapter is ../Certificated_Of_Degree_Backend.xml It works fine in Jaspersoft Studio But when I open the web and open the report i'll get error like this If I remove default data adapter it will return empty report I remove the data adapter and got error so it is the issue of default data adapter I just follow the tutorial and not work Any suggestion would be nice! thank you
