Hey, @amenyaj-8769!

It sounds like it could be an issue with environment variables. Are you still pointing to your local development environment, by any chance?

https://vercel.com/docs/projects/environment-variables

I also recommend checking out this thread on how to get good answers from the community: community.vercel.com/t/how-to-get-good-answers/158

I have rechecked the enviroment variable and ensured they are all added but still experiencing same issue. Can you look over my environment variables and see if there's any missing or entered incorrectly?

I am receiving the following messages below, but when I check the variables, these are all present. Is there another place I need to check and update? - I have attached what I have in there

❌ FAILURE: Production environment has critical errors. 🛑 Fix all errors before attempting deployment. Errors:

1. Required environment variable NEXT_PUBLIC_APP_URL is missing
2. EMAIL_HOST contains localhost in production

Could you try and debug with some logs?

1
// Add logging to identify the issue
2
console.log('Auth environment:', {
3
  url: process.env.NEXTAUTH_URL,
4
  hasSecret: !!process.env.NEXTAUTH_SECRET,
5
  environment: process.env.NODE_ENV
6
});

This is the error that generates when I run the logs:

Check for Vercel environment

if [ ! -z "$VERCEL" ]; then echo "" echo "☁️ VERCEL DEPLOYMENT DETECTED:" echo " VERCEL_ENV: ${VERCEL_ENV:-"Not set"}" echo " VERCEL_URL: ${VERCEL_URL:-"Not set"}"

    echo "🚨 CRITICAL: Production Vercel deployment without NEXT_PUBLIC_APP_URL"

Still need support on this issue. I have tried all the suggested solutions but I am not getting it to work.
