Vapi-n8n Integration Breakdown - Voice Agent Stalling at Tool & Webhook Fail

For some reason Vapi and n8n aren't connecting together in my workflow, it was working perfectly fine for days, then all of a sudden in Vapi when it comes to the "getPropertyData tool" the Voice Agent just stops talking at this point. n8n is not picking up the trigger either and when I test Vapi nothing comes through in the executions anymore. The production URL from the webhook in n8n is connected to all of the tools in VAPI too. I am not sure why n8n and Vapi have just stopped connecting together, if you can help ASAP id appreciate it. I noticed others have add a similar issues in the last couple of days with connecting n8n and Vapi. See images attached.

Hi, why are you giving general instructions in the prompt instead of a clear question in the first message? I'm interested because my bot doesn't stick to the list of questions and starts asking the wrong thing

Could you please provide a loom screen recording of the issue? We would like to investigate this and find a solution for this.

Yeah it got passed the tool section and it is responding, but it doesnt collect the data correctly from googlesheets which is connected to n8n

Could you send over a call ID? That would really help us figure out why the assistant isn't collecting the data correctly.

Hi Kyle, my call ID is: 95a2a73e-c7a4-4b3a-95f4-5dadc8ba3d5e

Are you referring to the getPropertyInfo tool? I can see the result it returned but it doesn't look like a desirable result, unless that is intentional
