assistant stops speaking, twillio call

Your assistant is likely stopping mid-call due to webhook errors ("Invalid webhook type").
Make sure your webhook handler processes all event types sent by Vapi. Here’s a Node.js/Express example:

app.post('/webhook', async (req, res) => {
  const { type } = req.body;
  if (!['assistant.started', 'speech-update', 'status-update'].includes(type)) {
    return res.status(400).send('Invalid webhook type');
  }
  // Handle events here
  res.status(200).send();
});

app.post('/webhook', async (req, res) => {
  const { type } = req.body;
  if (!['assistant.started', 'speech-update', 'status-update'].includes(type)) {
    return res.status(400).send('Invalid webhook type');
  }
  // Handle events here
  res.status(200).send();
});

app.post('/webhook', async (req, res) => {
  const { type } = req.body;
  if (!['assistant.started', 'speech-update', 'status-update'].includes(type)) {
    return res.status(400).send('Invalid webhook type');
  }
  // Handle events here
  res.status(200).send();
});

app.post('/webhook', async (req, res) => {
  const { type } = req.body;
  if (!['assistant.started', 'speech-update', 'status-update'].includes(type)) {
    return res.status(400).send('Invalid webhook type');
  }
  // Handle events here
  res.status(200).send();
});

Update your Vapi dashboard to point to your public webhook URL (e.g., from ngrok) and ensure your handler accepts all relevant event types.
