Anyone else having this issue or have solved it? Make webhook returns: {results: [{ "result": "Here's what's available: On March 10th, the available time slots are 9:00 AM, 10:00 AM, 11:00 AM, 12:00 PM, 1:00 PM, 2:00 PM, and 4:00 PM.", "toolCallId": "call_WB4FKM69vcysFFtdZs7BiZGi" }] } here's the log: { "name": "calGetSlotsByDate", "role": "tool_call_result", "time": 1741444435525, "result": "No result returned.", "toolCallId": "call_WB4FKM69vcysFFtdZs7BiZGi", "secondsFromStart": 18.808 } Anyone else having the same issue or have solved it?

Hi there! I see you're having an issue with the VAPI tools function not receiving your returned results JSON. Based on what you've shared, I can spot a few potential issues: 1. **JSON Format Issue**: Your webhook response is missing quotes around the

results

key. The correct format should be:

json
{"results": [{
  "result": "Here's what's available: On March 10th, the available time slots are 9:00 AM, 10:00 AM, 11:00 AM, 12:00 PM, 1:00 PM, 2:00 PM, and 4:00 PM.",
  "toolCallId": "call_WB4FKM69vcysFFtdZs7BiZGi"
}]}

2. **Content-Type Header**: Make sure your webhook response has the

Content-Type

header set to

application/json

. This is crucial for proper processing of the JSON payload [source](https://discord.com/channels/1211482211119796234/1211483291191083018/1327234509126165615). 3. **Recent Schema Changes**: VAPI recently updated their

ToolCall

schema, replacing properties like

tool

and

toolBody

with

function

and

id

details. Make sure your implementation reflects these changes [source](https://docs.vapi.ai/changelog). 4. **Line Breaks**: If your result string contains any line breaks, ensure they're properly escaped with

\\n

[source](https://discord.com/channels/1211482211119796234/1211483291191083018/1334658296291921920). 5. **Synchronous vs Asynchronous Configuration**: Check if your tool is configured as synchronous or asynchronous, as timing issues could lead to "No result returned" messages [source](https://discord.com/channels/1211482211119796234/1211483291191083018/1342336047589359618).
