hi, i am trying to integrate vapi in an application i build in replit and cursor, i am encountering persistent errors and my tech knowledge is limited, can anyone help me out here

@nithish Hello! I'd be happy to help you with integrating VAPI into your application. Could you please provide me with more details about the errors you're encountering? Knowing the specific error messages or the part of the integration process where you're facing issues would be very helpful in assisting you further.

this is the error vite] connecting... [vite] connected. Response {data: null, error: {…}} data: null error: Object [[Prototype]]: Response

@nithish It seems like you're experiencing a connection issue with Vite, which is likely related to the development server setup in your Replit environment. The error message indicates that the server is trying to connect, but there's an issue that's preventing a successful connection, resulting in a

null

response. To better assist you, I would need to know the following: 1. The exact steps you're taking when you encounter this error. 2. The code snippet where you're trying to integrate VAPI. 3. Any additional configuration you've done related to Vite or your development environment. Once I have this information, I can provide you with more targeted assistance. If you're not comfortable sharing code snippets or details here, please ensure that you've followed the integration documentation provided by VAPI accurately, and consider reaching out to their support for more specific guidance.

1) 1. Steps Taken in Code/Environment: - Implemented Vapi.ai Web SDK integration using @vapi-ai/web package - Set up environment variables in client/.env.local for VITE_VAPI_API_KEY and VITE_VAPI_ASSISTANT_ID - Added CORS headers in Express server (server/index.ts) - Created a VapiClient initialization module (client/src/lib/vapi-client.ts) - Implemented webhook endpoints in Express routes (server/routes.ts) - Using Vite as the development server with Express backend on port 5000 2. Relevant Code Implementation: Main Vapi Client Implementation: typescript import { VapiWebClient } from '@vapi-ai/web'; class VapiClientError extends Error { constructor(message: string) { super(message); this.name = 'VapiClientError'; } } export const createVapiClient = () => { const apiKey = import.meta.env.VITE_VAPI_API_KEY; if (!apiKey) { throw new VapiClientError('VITE_VAPI_API_KEY is not defined'); } try { const client = new VapiWebClient({ apiKey, }); return client; } catch (error) { console.error('Failed to initialize Vapi client:', error); throw new VapiClientError(Initialization failed: ${error.message}); } }; : 3) 3. Development Environment Configuration: - Running in Repl.it environment - Using Vite for frontend development - Express server running on port 5000 - Development environment variables configured through .env.local - CORS enabled for all origins (*) - Full-stack setup with Express serving both API and static files Error Details: javascript Response { data: null, error: {...} } Additional Context: - The error occurs immediately after attempting to connect to Vapi services - The response contains a null data field - Using the latest version of @vapi-ai/web SDK - The application is running in a Repl.it environment which might have specific networking constraints

Hey @nithish can you host your code over github and share the github repo, without actually trying out the code it's hard for me to tell exactly where error has occured? Do let me know your thoughts on it.

Sure
