@sap/cds-odata-v2-adapter-proxy deployment successful service returns 404

[former_member677781]

I built and deployed my app with odata v4, then added adapter module for odata v2 and deployed on CF
1- Odata v4 works fine ( tested with single entity )
2- Odata v2 works with but with adapter's URL not with the proxy url.

Adapter Startup Logs:

This return v2 metadata
https://<>-adapter.cfapps.sap.hana.ondemand.com/v2/odata/v4/Service/$metadata

Anything with Proxy i.e. with service URL returns 404

https://<>-service.cfapps.sap.hana.ondemand.com/v2/odata/v4/Service/$metadata

Any pointers on what I could be missing ?

If I'm getting it right, your V4-Service should be located here:
https://<>-service.cfapps.sap.hana.ondemand.com/odata/v4/Service/$metadata - in the links mentioned above, you included "/v2" in both the proxied and the unproxied URL, but this should only be part of the proxied one.
