[Jasperreports Web Studio 2.0 preview not working]

Hello  

I'm trying to use Jaspersoft Web Studio 2.0, downloaded from https://www.jaspersoft.com/products/jasperreports-web-studio

I have added into start.sh java args to use it without login and use test-dir as repository 

JRWS_ARGS="-Djrws.https.allow.certificate.selfsigned=true -Djrws.hide.login.buttons=true -Djrws.repository.file.test-dir=/Users/mstatkevych/Projects/jasperreports-web-studio-pro-2.0-2.0/test-dir"

 

when I'm trying to use preview it shows that report is empty 

 

 

I do not understand  what should I do to see preview
