UI5 application - unable to connect to on-premise backend system

[former_member547215]

Hi guys

I am currently working on a POC developing a simple UI5 app on the Trail server of SAP Cloud Platform (SCP).

Checklist:

1. I already developed OData Service in the backend system.

2. I have installed SAP Cloud Connector (SCC) on my desktop.

3. The SCC connects to SCP successfully using S username.

4. The SCC also has internal/backend systems mapped successfully and an OData resource made available.

5. The internal/backend system is visible in Cloud Connectors page of the SCP.

6. I have created a destination in SCP of type HTTP, Proxy Type OnPremise and with URL pointing the exposed backend system (http://virtualhost>:8010.

7. I have created a UI5 app using SAP Web IDE and its deployed in SCP.

When I run this app, I am getting the following error:

Failed to load resource: the server responded with a status of 503 (Service Unavailable) /destinations/ECD/sap/opu/odata/SAP/ZSD_MATR_ODATA_PRJ_SRV/$metadata?sap-language=EN

What seems to be missing/wrong and causing this problem?

Thanks guys.

Hi Saleem,

I am also facing same issue. not able to consume OnPremise metadata. I have done all the setting as per document.

Hi Saleem,

Make sure ZSD_MATR_ODATA_PRJ_SRV is activated in SICF node.

Also make sure adt (ABAP developer tools) node is activated in SICF. This enables any app to run on WebIDE.

Have you defined the destination in the neo-app.json? and then the datasource and model in the manifest.json? can you include those bits of code?

Hi Brian

Thanks for your reply mate.

I have made progress but still not through.

The metadata request from UI5 is getting thru but nothing is happening after that as in UI5 doesn't seem to be making a query using the metadata which it was attempting atleast until yesterday. In the network tab, the last call I see if fetching of metadata and nothing else. Any idea/tips?

on online hcp webide check you possible to import project from gateway?

in gateway client , able to see any data?

How do you import Gateway project into HCP?

In gateway client the project is working fine, returning the desired results of all CRUDQ operations. Even the HCP URL for the OData service responds but the app itself has gone mute. I have recreated the app step by step but same behaviour.
