05/07/2025, 4:10 PMBased on your issue with empty arguments in tool calls, this could be due to incorrect variable handling. Check your variable referencing and interpolation syntax in your tool configuration.
Here's how to debug:
1. Go to the [Vapi Dashboard](https://dashboard.vapi.ai/calls) and locate your call using the ID you provided
2. Verify your tool call response format follows this structure:
Copy code
json
{
"results": [{
"toolCallId": "your-actual-tool-call-id",
"result": "Your response data"
}]

05/07/2025, 4:11 PMCheck your tool call response format - it should be properly structured JSON with the correct `toolCallId`:
Copy code
json
{
"results": [{
"toolCallId": "YOUR_ACTUAL_TOOL_CALL_ID",
"result": "Your result as a single-line string without line breaks"
}]

05/12/2025, 3:00 PMEnsure the first tool returns the correct toolCallId and result in its response, tools are properly configured, and your backend correctly handles and forwards data between chained tools.

05/16/2025, 5:06 PMi do not want backedn to handle it
hxrdxk
05/16/2025, 5:07 PMinstead it must use the response of first tool which is now in its context, so it must use the context to create payload for next tool

05/16/2025, 5:07 PManyways i solved it by using different arch
