My n8n webhook cannot fetch the data from Vapi. It's calling the right tool, but for some reason there's connection between n8n and Vapi.
Here's a video of the error. Hopefully this helps! After the call ends you can fast forward a little bit. It takes me a minute to find the webhook error.
Below the json from the webhook request error:
