This appears to be a Function Invocation Failed error on Vercel, which typically occurs when there's an issue with your serverless functions. Let's troubleshoot this step by step:

1. First, check your server-side code for any potential issues:

Here are the steps to resolve this issue:

1. Check your serverless function logs:

   • Go to your Vercel dashboard
   • Select your project
   • Click on "Deployments"
   • Select the failed deployment
   • Click on "Functions" to view the logs

2. Common fixes:

   • Verify all required environment variables are set in your Vercel project settings
   • Ensure all dependencies are listed in your package.json
   • Check for infinite loops or long-running operations
   • Make sure you're properly handling errors in async functions
   • Verify your database connections and API endpoints

3. Development testing:

   • Test your serverless functions locally using vercel dev
   • Add more detailed error logging
   • Use try-catch blocks to handle potential errors

If you need more specific help, please share:

1. The relevant serverless function code
