All of tools for my inbound agent stopped working. I have been trouble shooting for hours, I can’t figure it out. My whole agent worked yesterday now none of my tools work. I have plenty of credits I have no idea. Has anyone had this happen? #1211483291191083018

Sorry to hear your tools stopped working! To help diagnose, could you please check your Vapi dashboard's Call Logs or API Logs and let me know if you see any specific error messages or patterns when the tools fail? This will help pinpoint whether it's a configuration, integration, or provider issue. If you need guidance on where to find these logs, let me know!

I am getting tool response no result returned. My call logs don’t show anything since me trying to run these tools so I’m assuming it’s not going through.

Which type of tools? Built in Vapi tools or custom functions?

I am using custom tools

I seem to be experiencing a similar issue. The AI Assistant will say it's fetching the data from a tool, and then it will go silent before asking, "Hello, are you there?" The call logs also don't show any tools being called. Is this your experience @Smiley ?

Mine just says no tools returned. It was literally working yesterday now it’s not and my call logs show nothing also

Okay, thanks for the reply. Mine was also working, and now it's not. I haven't found a way to trace what the issue may be.

Me either!

Just came to respond. Are you by chance using Squads for your assistant setup? I can't explain why, but once I converted my assistant from Squads to a single assistant. My tool calls started working again.

No I haven’t I don’t even know what squads are

Dang, okay. Hopefully, Vapi support will respond. Sorry, I'm not much more help. Going through my call logs surfaced nothing that stood out. No errors, either.

No result returned wouldn’t be a Vapi issue

Well the tools aren’t being called that’s the problem

Hi Smiley, It sounds like you're experiencing an issue with your custom tools not being called during your workflows. Here are some steps you can take to troubleshoot this: 1. **Check Response Format**: Make sure that your webhook returns the correct JSON structure. Specifically, ensure your response contains a

toolCallId

that matches the one provided in the tool request, and the

result

should be a single-line string without line breaks.

json
   {
     "results": [
       {
         "toolCallId": "your_toolCallId_from_request",
         "result": "Your single-line response"
       }
     ]
   }

2. **Verify HTTP Status**: Ensure that your server is returning an HTTP 200 status code for all tool responses. Any other status code might cause the response to be ignored. 3. **Inspect Call Logs and API Logs**: Check the

Call Logs

and

API Logs

in your Vapi dashboard. Look for any errors or missing tool call entries which can indicate why tools might not be executing as expected. 4. **Configuration Check**: Verify your tool configuration in the Vapi dashboard to ensure all required parameters are included and correctly set up. 5. **Review Dashboard Logging and Status**: Make use of Vapi's logging features to trace where the issue might be occurring. Ensure there are no service disruptions on the [Vapi Status Page](https://status.vapi.ai/). For more detailed guidance, you may refer to the [Custom tools troubleshooting](https://docs.vapi.ai/tools/custom-tools-troubleshooting) document. If these steps do not resolve your issue, let me know so we can further investigate.
