i tried invoking a tool call with variables collcted from previous conversation node but it didn't wrk ,why?this is the caller id:d85317b9-3a47-472e-8521-799d8be187b5

Thanks for sharing the caller ID. To help troubleshoot, could you specify which tool you tried to call and what variables you passed from the previous node? This will help identify if the issue is with variable mapping or tool configuration.

Ensure the variables are correctly stored, and match the tool’s parameter names, the assistant is instructed to invoke the tool, the tool is enabled in settings, and dynamic variables if used are passed via assistantOverrides.

they're stored infact i call them after each node for the same purpose just to confirm i am not missing anything

To help troubleshoot further, could you please specify the exact tool you tried to call and the variable names you passed from the previous node? This will help identify if the issue is with variable mapping or tool configuration. For reference, please ensure that variable names match the tool’s expected parameters and that the tool is enabled in your workflow settings ([Vapi Workflows Documentation](https://docs.vapi.ai/workflows)).

slotfinder tool

Looking into it

Suggestion: Double-check that the variable names you pass from previous nodes exactly match the parameter names expected by the

slotfinder

tool. For example, if your tool expects a parameter called

date

, ensure your previous node outputs a variable named

date

(not

selected_date

or similar):

json
{
  "tool": "slotfinder",
  "parameters": {
    "date": "{{date}}"
  }
}

If the names do not match, the tool call will not work as expected. See: [Vapi Workflows Documentation](https://docs.vapi.ai/workflows) Sources: - [Vapi Workflows Documentation](https://docs.vapi.ai/workflows) - [API Request Node](https://docs.vapi.ai/workflows/nodes/api-request)

hey tool call is still not working man ,it i don't get to hear the response ,it keeps looping at one instant why is this happening? caller id is :3f259229-24a8-412c-8b8f-f78a8b611f02

To help resolve the issue: Could you please share the exact variable names you are passing to the

slotfinder

tool, and confirm if they match the parameter names expected by the tool (e.g.,

date

)? This will help identify if the problem is due to variable mapping or workflow configuration. For reference, variable names must match exactly for the tool call to work as expected ([Vapi Workflows Documentation](https://docs.vapi.ai/workflows)).

any response so far?

Hey, sorry to hear about the issue with your account. Could you please record a loom video showing the error or behavior you're experiencing? It would really help us understand the problem better.

Feel free to book a slot from here
