HI
the endpoint https://hawo-mockbot4-token-app.blueriver-ce85e8f0.westus.azurecontainerapps.io/api/token/directline reply always with error 500 (Internal Server Error).

I copy the workspace in public folder ROOT of Apache tomcat and running this example..

Additional context

No response

Start by reproducing the request to the Azure endpoint /api/token/directline while loading samples/04.api/a.welcome-event/index.html from the Tomcat deployment. Inspect the endpoint response and Azure-side configuration or logs, including the reported CORS behavior. Done means the endpoint no longer returns 500 and the sample displays a chat.
