Thank you

Nice Video. Can you explain the remote-call for odata srv of kind="odata-v2" for central-hub system from SAP CAP. It works for embedded landscape and not for central-hub.

[@somnathpaul2020]

Thanks for watching the content and sharing the feedback. Now i m not sure what exactly the error that you are facing. In my opinion this is nothing to do with hub or embedded. Can you please check once if you can access from postman or BTP destination? If this erroring same or what you are getting there?

How to consume this on ui or via fiori?

[@somnathpaul2020]

Consumption is all about same approach that we do while integrating UI with any cap project, xan you please elaborate what exactly your question. Thanks.

[@adityapratap7696]

Ok so as per the video,there are no entities here.when we run the app.only thing we observe ..is..metadata link..how.to use it to consume this in fiori/ui5 app.

[@somnathpaul2020]

​@@adityapratap7696i think you can make some ajax call at fiori side following /getToDo() or /createToDo() Remember these are called function imports. Pls check one more time testing section where i showcased how to call the endpoint over .http fike. I hope this can give you some ideas.

​@@somnathpaul2020 Could you please give one session on implementation of error handling in the backend. I have seen people do not use it in the backend or at the best they are using console.log() which is not the correct way. Coming from the ABAP background it's very irritating for me to not be able to raise the errors properly and pass a meaningful message. It would be very helpful of you if you do the session on backend error handling😅. Great session on api implementation by the way. Will try this week and let you know😊

@ankitgarg8595 backend means i understood from abap side right? If so then in abap we have technical and functional exceptions.. we can use it .. any challenge you are facing? BTW thanks for watching and sharing your feedback.
