Answer

The error message "Cannot read properties of undefined (reading 'message')" typically suggests that there's an attempt to access a property of an object that hasn't been defined or initialized yet in your Next.js application. This kind of issue often arises due to the code trying to use an object or variable before it has been properly established or returned from an asynchronous operation.

Without specific details from the official documentation or error messages directly related to Vapi from the provided information sources, a general advice would be to:

Ensure that any variables or objects you're trying to access are correctly initialized before you try to use them.
Check if the issue arises from server-side code trying to access browser-specific objects like navigatornavigator or windowwindow, which are not available in a server-side context like Vercel's serverless functions. This is a common issue with server-rendered applications and might require conditional checks to ensure code execution only happens in the browser environment.

For more detailed debugging, inspect the serverless function logs in your Vercel dashboard, which might give you more insight into what's causing the error. Additionally, reviewing the part of your code referenced in the error message and ensuring that all asynchronous operations are correctly awaited can help identify the cause.

Given the nature of your issue, it might also be helpful to review common Next.js practices for handling serverless functions and accessing API endpoints to ensure your implementation aligns with expected patterns.

Since this response doesn't directly address a Vapi-related question and no specific documentation from Vapi matches this context, it's based on general web development practices.
