Hi, i imported a Twilio number into my Vapi account and connected it to one of my agents. The Twilio number now has the default webhook request configured (https://api.vapi.ai/twilio/indound_call). But when i call my number it says there has been an application error and hangs up. In Twilio's error logs it says there has been a HTTP retrieval failure as the webhook returned a 404 error message. How do i fix this so when i call my twilio number my agent picks up?
