Hi can anyone assist? I’m integrating the @Vapi-ai/web SDK into my Next.js app to run an AI voice interview assistant. When I call await vapi.start(assistantOptions), it throws an unhandled error with no useful message: javascript Copy Edit Error: Unhandled error. (undefined) I’m initializing the SDK like this: js Copy Edit const vapi = new Vapi(process.env.NEXT_PUBLIC_VAPI_PUBLIC_KEY);
