No data in app - failed to create cache

Hi guys,

I deployed the app from the openSAP CAP course week 3 - unit 5. The srv-app works fine (displaying the metadata and the actual data) but when I try to start the app / UI - application the three different apps (browse, manage books, manage orders) do not show any data. In the console of the inspector I receive a 'Failed to create cache for binding sap.ui.model.odata.v4.ODataListBinding: ...'.

Why does the error occur? How do I resolve the error?
