River tutorial code works on cloud but not on premise?

I can explore the tutorial code and generate data on the cloud at SAP River - Tutorials

I copied the Show Business code (SAP River - Show Business Tutorial) into an .rdl file in my River project. However, when I try to view Data Preview or Generate Data I receive the following error:

Cannot open data preview; the server returned an unexpected result: Error code 404 - Bad Identifier: HelloRiver.Movie {"error":{"code":"","message":{"lang":"en-US","value":{"type":"ODataInputError","message":"Bad Identifier: HelloRiver.Movie"}}}}

I've tried making a simple HelloWorld project as well, but I receive the same error for a different entity.

Any help would be very much appreciated!
