My tool call is being called however I get a 500 server error. When I look at the webhook logs and I copy and paste the request into the tool test it works. Plz help is a critical functionality

Hi there! 👋 I see you're experiencing a 500 server error with your tool call in Vapi. I don't have access to your specific logs for call ID af9a291d-3568-4892-9ddd-ef979899ef19, but I can definitely help you understand why your tool call might be working in the test environment but failing in production. Based on the information I found, here are some common causes for this issue: ## Response Format Issues One of the most common causes is incorrect response formatting. When Vapi makes a tool call: - The JSON response must be correctly formatted with the proper

toolCallId

and

result

fields - The

toolCallId

in your response must match the one sent by Vapi in the initial request - The

result

must be a single-line string without any line breaks According to [documentation](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1325000684231196775), mismatched

toolCallId

values are a frequent cause of errors. ## Environment Differences There are several differences between the test and production environments that could explain this behavior: - **Tool Configuration**: The tool might be set to

async

mode in production but

synchronous

in the test environment - **Network Accessibility**: Your server might be accessible in the test environment but not properly configured for production requests - **Request Handling**: Production environments often have different rate limits, timeouts, or concurrency settings ## Debugging Steps 1. **Check Webhook Logs**: Review the logs for details about the failed request, including: - The exact error message - The request payload - The response (or lack thereof) 2. **Compare Request Details**: Since you mentioned the request works when copied to the tool test, compare: - Headers - Authentication - Request body format - Response timing 3. **Server Logs**: Check your server logs for any errors that might be occurring when Vapi makes the request in production

Is there somewhere I can change the timeout settings of tool calls or see if that would be the problem

checking if this is resolved/solved for you?
