Default data adapter serverside Error

[lalalalaluk]

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
