VAPI does not process n8n output

Hello veryone, i have a vapi problem which I hope someone here has allready dealed with this kind of problem.
Situation:
Vapi send customer name to n8n, n8n uses that name and todays' date to look in an google sheet for that specific name and return an answer based on the information in the excel sheet.
n8n works great. n8n handles the customers name goes trough the workflow and returns this:
[
{
"found": true,
"customerName": "Jan",
"product": "Scooter green",
"status": "Bezig",
"expectedPickup": "14:00",
"recordDate": "8-8-2025",
"matchReason": "Meest recente record gevonden (8-8-2025)",
"message": "Your pie is ready, you can pick it up."
}
]
the problem is that VAPI does not get this information.
I allready configured in vapi this but it still does not process this information. What do I miss?
It keeps saying this in the logs: No result returned
{
"name": "Service_informatie",
"role": "tool_call_result",
"time": 1754734460046,
"result": "No result returned.",
"toolCallId": "call_3VQB9D7kYvheh6CFsCjQYsLW",
"secondsFromStart": 11.831
}
I think the problem lies within this screen. see attachment
I thought i should enter {{message}} so it can interecept the message. but also its not working
any one knows how to solve this?

Thanks. Ronald
