I was trying to fetch the current time from my backend through vapi but keep getting errors, can you tell me what went wrong? @app.post("/webhook") async def get_current_time(request: Request): try: # Parse the incoming JSON data request_data = await request.json() # Extract toolCallId if present tool_calls = request_data.get('message', {}).get('toolCalls', []) toolCallId = tool_calls[0].get('id') if tool_calls else None # Get the current time current_time = datetime.now().strftime("%H:%M") # Format the response response = { "results": [ { "toolCallId": toolCallId, "result": f"The current time is: {current_time}" } ] } return response except Exception as e: raise HTTPException(status_code=500, detail=str(e)) @Vapi a

@Shrey It looks like you've got the right idea for fetching the current time and returning it in your webhook response. However, if you're encountering errors, there could be a few reasons why this might be happening. Here are some common issues to check: 1. **JSON Parsing Errors**: Ensure that the JSON sent to your webhook is correctly formatted. If there's an error in the JSON structure, it could cause the
request.json()
call to fail. 2. **ToolCallId Extraction**: Make sure that the incoming request actually contains the
toolCalls
array and that it has at least one element with an
id
. If not, attempting to access
[0]
could result in an error. 3. **Datetime Import**: Verify that you have imported the
datetime
module correctly at the beginning of your script with
from datetime import datetime
. 4. **Server Issues**: There might be server-side issues unrelated to your code, such as network problems or configuration issues. 5. **Error Handling**: Your error handling is currently raising an HTTPException with the error message. While this is good for debugging, make sure that the client can handle these error messages correctly. 6. **API Key**: If your backend requires an API key for authentication and it's not being sent correctly, that could also result in an error. 7. **VAPI Configuration**: Ensure that your VAPI configuration is correct and that you're sending the request to the right endpoint with the proper headers. If you're still unable to resolve the issue, please provide the specific error message you're receiving, and I'll do my best to assist you further. If the error message contains sensitive information, consider asking support for more info on this.
You can continue this conversation by mentioning me in the message.

I am getting 405 metthod not allowed @Vapi
v
@Shrey A
405 Method Not Allowed
error indicates that the HTTP method you are using to make the request to the server is not supported by the resource. In the context of your webhook, it seems that the server is rejecting the POST request made to the
/webhook
endpoint. Here are a few steps you can take to troubleshoot this issue: 1. **Check Server Configuration**: Ensure that your server is configured to accept POST requests at the
/webhook
endpoint. If you're using a framework like Flask or Django, make sure you've decorated the function with the correct method (e.g.,
@app.route('/webhook', methods=['POST'])
for Flask). 2. **Review API Documentation**: If you're calling a third-party API, double-check their documentation to make sure you're using the correct HTTP method for the endpoint you're trying to reach. 3. **Inspect Request Source**: If you're not the one making the request, inspect the source of the request to ensure it's using the POST method and not GET or another HTTP method. 4. **CORS Policy**: If you're making the request from a web browser, ensure that the server's CORS policy allows POST requests from the origin you're sending the request from. 5. **Firewall or Proxy**: Sometimes, a firewall or proxy can block certain HTTP methods. Verify that there are no such blocks in place. 6. **Test with a REST Client**: Use a REST client like Postman or curl to manually send a POST request to the
/webhook
endpoint to see if you can reproduce the error. This can help isolate whether the issue is with the client or the server. If you've checked all of these and the issue persists, you may need to provide more details or consult with your server administrator or hosting provider for further assistance.

Hey @Shrey To help track down this issue, could you share: - The call ID - When exactly this happened (the timestamp) - What response you expected to get - What response you actually got instead This would really help me figure out what went wrong!
