Error during compilation of odata proxy

[Martin_Böschen]

Hello,

I'm following the course https://learning.sap.com/courses/building-apps-with-the-abap-restful-application-programming-model and I'm stuck in week 5, unit 2.

I keep getting the error 

"Error during compilation of '$OPROXY_SRVD#ZSC_RAP_AGENCY_1848'."

The error is thrown from the following code:

    DATA service_consumption_name TYPE cl_web_odata_client_factory=>ty_service_definition_name.

    DATA(http_destination) = cl_http_destination_provider=>create_by_url( i_url = 'https://sapes5.sapdevcenter.com' ).
    http_client = cl_web_http_client_manager=>create_by_http_destination( i_destination = http_destination ).

    service_consumption_name = to_upper( 'ZSC_RAP_AGENCY_1848' ).

    odata_client_proxy = cl_web_odata_client_factory=>create_v2_remote_proxy(
      EXPORTING
        iv_service_definition_name = service_consumption_name
        io_http_client             = http_client
        iv_relative_service_root   = '/sap/opu/odata/sap/ZAGENCYCDS_SRV/' ).

My service consumption model is generated from the metadata on https://sapes5.sapdevcenter.com/sap/opu/odata/sap/ZAGENCYCDS_SRV/, so everything should fit together.

What could be the problem?

PS: Feel free to look in the code in the Abap Trial Platfrom.

Best Regards,

Martin

So I'm not the only one that has this problem with the unit in the training course.

I believe it has something to do with the age of the course, being from 2020, and the changes to the development methodology of RAP since then.

Hint:
The example does not work on an on-prem system because the Service consumption model there does not allow OData services. Only RFC and WebService.
