VAPI IS NOT A CONSTRUCTOR ERROR

[atharva-64]

App.jsx:11 Uncaught TypeError: Vapi is not a constructor
at App (App.jsx:11:14)

I am using vapi's latest version i.e 2.5.1. i am not being able to fix the issue. Whenever i write const vapi= new Vapi(public_api) i get this error 'vapi aint a constructor' and when i do const vapi=Vapi(public_api) i get this error 'vapi aint a function'

I am using vapi 2.5.1 version . All I want is to make a start call button int the ui and whenever i click on that i wanna talk to vapi ai. And with transcripts i wanna update dahsboard, generate call summaries, etc etc. I tried reinstalling package, downloading client-sdk but nothing worked. Here is my code anyone please fix it

import * as Vapi from "@vapi-ai/web"
import React from "react"

const VITE_VAPI_FRONTEND=import.meta.env.VITE_VAPI_FRONTEND
const VITE_VAPI_ASSISTANT=import.meta.env.VITE_VAPI_ASSISTANT
const WORKFLOW_ID=import.meta.env.VITE_WORKFLOW_ID

function App(){
const vap= new Vapi(VITE_VAPI_FRONTEND)
vap.start(VITE_VAPI_ASSISTANT)
vap.on('call-start',()=>console.log('Call has started'))

return (<>

Vapi 2.0

Start Stop ) }

export default App;
