I am using Next.js with Firebase Hosting integration.

Environment variables in .env are set correctly.

I already tried:

Cleaning build cache (rm -rf .next && npm run build)

Checking Node.js version

Removing unused experimental flags

Verifying my config export format

Request

Can you someone help me to sort out the solution
