Problem with proxy to consume HANA XS OData in Hana Cloud Trial account

Hello experts,

I'm following SIMMACO FERRIERO's post How to consume a HANA XS service on the HANA Trial landscape creating Gregor Wolf's proxy with node.js to expose the HANA XS Odata service I've created.

I am able to start the proxy normally

But when I try to call my Odata service via the proxy I get following error:

http://localhost:7891/s0005549254trial/dev/myproducts/services.xsodata/$metadata

Does anybody have an idea why this happens?

Thanks for your help.

Regards,

Jaime
