Drizzle ORM Type Generation Failed

1. DATABASE_URL not set or pointing to unreachable database
2. drizzle.config.ts has incorrect database credentials
3. Database server not running or firewall blocking access
4. Invalid schema or table definitions in Drizzle schema file
5. Wrong database dialect (postgres vs mysql vs sqlite) specified

Verify DATABASE_URL: Check .env.local contains correct database URL matching drizzle.config.ts datasource.

Test connection: Use database CLI to verify direct connectivity before running Drizzle commands.

Check drizzle.config.ts: Ensure dialect matches your database: dialect: 'postgresql' for Postgres, 'mysql' for MySQL.

Generate types manually: Run drizzle-kit generate:pg --schema=./schema.ts specifying your dialect explicitly.
