webhook:
Your server rejected `assistant-request` webhook. Error: timeout of 7500ms exceeded
According to the timestamps you provided, your server received the request at 00:31:56 and the call ended at 00:32:03, which is about 7 seconds later. This aligns with the 7500ms (7.5 seconds) timeout mentioned in the error message.
According to [troubleshooting information](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336345690393149452), this could be caused by:
1. **Server response time**: Your server might be taking too long to process the request and respond
2. **Network delays**: There might be network issues between VAPI and your server
3. **Server load**: Your server might be under heavy load, causing it to miss incoming webhook calls
## The "r is undefined" Error
The "r is undefined" error you're seeing in the dashboard is likely related to the missing call logs. According to [error information](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1344328162024362095), this could be caused by:
1. **Outdated daily-js version**: The error might be related to using an outdated version of the daily-js library
2. **VAPI UI bugs**: The VAPI UI has known bugs that could be causing this error
## Troubleshooting Steps
Here are some steps you can take to debug this issue:
1. **Check your server logs**: Look for any errors or slow response times in your server logs during the time of these failed callsVapi Support Bot

webhook. According to [webhook information](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1336345690393149452), you should aim to respond within the 7.5-second timeout period
3. **Check webhook delivery logs**: According to [debugging information](https://discord.com/channels/1211482211119796234/1211483291191083018/threads/1334280135683084328), you can access webhook delivery logs through the VAPI dashboard to see if there are any issues with webhook delivery
4. **Test your endpoint manually**: Try to trigger the webhook manually using a tool like Postman or cURL to verify that it's operational and can receive data as expected
5. **Simplify your response**: If your server is doing complex processing before responding, try simplifying it temporarily to see if that resolves the timeout issue
6. **Check network connectivity**: Ensure there are no network issues between VAPI and your server
Is there anything specific about your server setup or the processing you're doing during the assistant-request
webhook that might be causing delays?

parameter
You can use a PATCH request to update the timeoutSeconds
parameter in your assistant configuration:
bash
curl -X PATCH 'https://api.vapi.ai/assistant/{assistant_id}' \
-H 'Authorization: Bearer YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{
"server": {
"url": "https://your-server-url.com",
"secret": "your-secret-key",
"timeoutSeconds": 20,
"headers": {
"custom-header": "header-value"
}
}
}'
This would increase your timeout from the default 7.5 seconds to 20 seconds, which should accommodate your process that's taking around 8-9 seconds to complete.
## Option 2: Update via analysisPlan.structuredDataRequestTimeoutSeconds
Alternatively, you can update the analysisPlan.structuredDataRequestTimeoutSeconds
setting:
1. Go to the API documentation: https://docs.vapi.ai/api-reference/assistants/update-assistant
2. Copy your private key from the dashboard: profile > api keys > private api key
3. Make changes to the analysisPlan
object, setting structuredDataRequestTimeoutSeconds
to 20s
4. Make sure to include all previous values along with this new timeout value
## Option 3: Contact Vapi Support
If you need specific adjustments or are having trouble with the API methods, you can contact Vapi support directly to discuss customization options for your specific use case.
Would you like me to provide more details on any of these methods?
