How to access application with app/router

[grathi1988]

I have build 2 UI5 apps. one with app/router and one without app/router folder configuration.

I deployed both the apps, but I am unable to access application with app/router. Is there any extra config changes I need to do apps with app/router in mta.yaml?

Staging application "SourcingTool"...
Application "SourcingTool-db-deployer" staged
Application "SourcingTool-srv" staged
Executing task "deploy" on application "SourcingTool-db-deployer"...

Skipping deletion of services, because the command line option "--delete-services" is not specified.
Process finished.
Use "cf dmol -i ca78d1e5-76ad-11ef-8765-eeee0a8b050c" to download the logs of the process.

here is my mta.yaml.

Hi

Please check this 

Correct Path: Ensure `path: app/router` points to the right folder with `xs-app.json`.

2. Check `xs-app.json`: Confirm it has correct routes configured.

3. Destinations: Verify that all required destinations (like `srv-api`) are properly set up and accessible.

4. Health Checks: Ensure readiness checks are configured for the app router.

5. Review Logs: Check application logs for specific errors during startup or access attempts.

Redeploy the MTA after verifying these points.
