UI5 App deployment error in S/4 Hana Public Cloud System

[nirmalsaini]

We have created the Communication Arrangement for Scenario SAP_COM_0104. We are using API_PRODUCTION_ORDER_2_SRV and API_PROD_ORDER_CONFIRMATION_2_SRV in our custom UI5 app for fetching and posting the data in the S/4 HANA Public Cloud. We have maintained the destination for this API. The application is working perfectly fine. We are trying to deploy the custom app to the same S/4 HANA Public Cloud system from which we are fetching the data, but it is failing to deploy.  We tried to deploy the application in both development and customizing tenant.

--- Steps to Reproduce ---

1. Create Communication Arrangement for Scenario SAP_COM_0104.
2. Maintain the destination in BTP, and check the connection
3. Goto BAS and create the Fiori App using the template, select the system as the destination created in the previous step. Select the entity and create the app. 
4. Open integrated terminal in the app and execute command "npm run deploy".
5. Deploy will fail.

Thank you for your question, @nirmalsaini.

Based on the scarce context provided I won't be able to do a proper analysis. But here is a tutorial that describes in some detail how to deploy an app you develop in SAP BTP to your SAP S/4HANA Cloud Public Edition. It might require a few more steps than what you had mentioned:

If this solves your request, please mark accordingly. Thank you.
