The build error is occurring because the Neon database connection string (DATABASE_URL) environment variable is not available during the build process. Let me fix this by making the database connection optional during build time and adding proper error handling.
The issue was that during the build process, Next.js tries to analyze all API routes, but the DATABASE_URL environment variable wasn't available at build time. I've fixed this by:
sql client is only created if DATABASE_URL existsThe key changes:
const sql = neon(process.env.DATABASE_URL!) to const sql = process.env.DATABASE_URL ? neon(process.env.DATABASE_URL) : nullsql client in each routeNow the build should complete successfully, and once you add the DATABASE_URL environment variable in your Vercel deployment settings, the database functionality will work properly.
