Vapi's provided sample code is also not running in my chrome I don't know I did chatgpt and many things but it's not fixing if does directly accessing the Vapi from loclhost is not possible?

Direct access to Vapi from localhost isn't possible because Vapi needs to reach your server via the open internet. You'll need to use a tunneling service like ngrok to create a publicly accessible URL:

bash
# Install ngrok
npm install ngrok -g

# Start your local server (example on port 3000)
# Then expose it with ngrok
ngrok http 3000

Copy the generated ngrok URL (https://xxxx.ngrok.io) and use it as your server URL in the Vapi dashboard. Source: - [Developing Locally](https://docs.vapi.ai/server-url/developing-locally)

Try using a custom domain for localhost, setting up a development proxy, or configuring CORS headers on the server.
