I created an AI voice agent for a dental clinic using VAPI AI, and I integrated it with n8n to check availability and book appointments. The process works perfectly in n8n, and the webhook response confirms the appointment is booked. However, the VAPI voice agent still says "not available" on the call, even when n8n indicates the appointment was successfully booked.

I have 10 content suggestions from a Split Out node . My Loop Over Items node is using {{ $json["message.content.suggestions"] }} expression but shows "No properties" and "No output data in this branch".How do I correctly set up this node to iterate through my content suggestions?
