Query tool only returning 'Success' and nothing el...

Chat ID: c64d3f0e-0683-4ddd-9c9d-7f2dbf0a26ba Time stamp: Sep 17, 2025 22:03 The response I expected is the chat bot able to retrieve the correct information from the KB and provide it back to the user. The response I received looks like it is a message 'Success' with no other details. I have uploaded a JSON file and added it to query tool so that it can look up information in the file by matching the provided ID to the same ID in the KB. I was debugging on the calls but it seemed to provide more information on the chats and I could see the function calls. I have even asked the AI assistant questions on other chats and this is what is said - "You are right to ask for clarification. The actual response from the query_triumph_physio_business_data call was simply "Success." without any detailed data included in the message. This means I did not receive the specific business, appointment type, or practitioner details from that call." https://cdn.discordapp.com/attachments/1417845520587686000/1417845520940011580/image.png?ex=68cbf70a&is=68caa58a&hm=1343b8b0a9cd74bc976c7360d23220bf940cf0bd75a8386811116f5b4b7b6431&

Suggestion: Check that your query tool's response is mapped to return the actual data from your knowledge base, not just a generic message. In your tool's server response, ensure you return the result in this format:
Copy code
json
{
  "results": [
    {
      "toolCallId": "YOUR_TOOL_CALL_ID",
      "result": { "your_expected_data": "value" }
    }
  ]
}
Update your server or tool configuration to include the detailed data in the 
result
field, so the assistant can access and relay it to the user. Source: - [Custom Tools Server Response Format](https://docs.vapi.ai/tools/custom-tools#server-response-format-providing-results-and-context)
c
Please disable 
async
option on your tool and it should produce the results from the tool

The query tool on the online dashboard does not seem to have an option to disable or enable the async option? Do I need to update config via code?
c
There is currently no option for 
async
for the query tool
