Dear SAP Experts,
I played through the tutorials of Jhodel Cailan and successfully retrieved data from Northwind API (v2 and v4).
Here is the blog: https://blogs.sap.com/2020/05/27/cap-consume-external-service-part-2/
My basic question is relevant for every API, since I am not able to show these instances within the CAP Fiori Preview.

This is how the list looks like: "No data found", even after clicking on "Go". And I also annotated the service.cds accordingly, which can be seen by the line item labels and selection parameters. By using CSV for products, it works, but when I use real service, FIORI preview doesn´t work anymore. Do you possibly have any idea? Thank you in advance.
