Error debugging XS Script from HANA Studio

Hi,

I can't start the Remote Javascript debugger from within HANA Studio.

I have created a XS javaScript debug configuration. Server and port is correct.

When I start the debugger I get the following error message:

Source locator does not exist:

1. com.sap.ndb.studio.xse.debugger.core.launching.XSDBGSourceLookupDirector

HANA Studio version is 1.80.3.

Anybody facing the same problem?

Thanks for your help.
