fastapi.exceptions.HTTPException: 500: Internal Server Error

ERROR: Application startup failed. Exiting.

Beginne in src/backend/src/semantic_kernel_orchestrator.py bei initialize_agents, insbesondere in Zeile 255, und verfolge den Client, der von semantic_kernel_app.py erstellt und verwendet wird. Prüfe die AgentsOperations API des installierten SDKs und den Pfad zur Agenteninitialisierung. Als erledigt gilt die Aufgabe, wenn die Container-App den Start des Lifecycles ohne das get_agent AttributeError oder den daraus resultierenden HTTP 500 abschließt.
