Hello everybody,

I share more information about my cap app.

• Testing locally.

ERROR: Could not find service binding of type 'destination'. This might cause errors in other parts of the application.

Error 1: Error during request to remote service: Failed to load destination.

Error 2: Error during request to remote service: Failed to load destination. Caused by: No user token (JWT) has been provided. This is strictly necessary for 'PrincipalPropagation'.

Error 3: Authentication kind "xsuaa" configured, but no XSUAA instance bound to application. Either bind an XSUAA instance, or switch to an authentication kind that does not require a binding.

Error: 4: No service matches destination

• MTA confi about service instance.

• My destination config.

• Resources for my cap app from mta

What Gregor says.

You have no destination service bound to your cap app. Look at this repo as example for the config: https://github.com/lemaiwo/ReCAPBTPServiceOverview/blob/main/mta.yaml

At line 28 the destination service is bound to the cap app which is instantiated at line 90

My app is bound when I tested locally. It returns a error.

When consuming external services with principal propagation you need to use a local approuter for testing. Can you maybe share it using git?

Hello Wouter, I notice my approuter instance, for instance propagate my user, but my service instance being not done. I'm trying to connect approuter instance by destination, it cloud not work. My context is that I build my CAP and UI5 apps separate. Moreover I connect these apps using OAuth2ClientCredentials throught destination using the url povides from Approuter instance but it returns 401 when i test my destination. When I use url provides from service instance the conenction is work, but no propagate my user.

Service Instance destination

It returns entities.

testing url provide from instance return 401.

Approuter Instance destination

No load nothing.

testing url provide from instance return data.

Do you have any idea to connect CAP and UI5 by separate using destitination?
