Drizzle ORM Type Generation Failed
Drizzle type generation fails with 'introspection failed' or 'unable to connect' errors when running drizzle-kit push or drizzle-kit generate. TypeScript errors appear because schema types aren't generated.
This happens when Drizzle cannot reach the database to introspect or generate types from your schema definition.
Error Messages You Might See
Common Causes
- DATABASE_URL not set or pointing to unreachable database
- drizzle.config.ts has incorrect database credentials
- Database server not running or firewall blocking access
- Invalid schema or table definitions in Drizzle schema file
- Wrong database dialect (postgres vs mysql vs sqlite) specified
How to Fix It
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.

I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

Get HelpFrequently Asked Questions
How do I set up drizzle.config.ts?
Create config with your database dialect and schema path: export default defineConfig({ schema: './schema.ts', dialect: 'postgresql', dbCredentials: { ... } })
Should I commit generated types?
Yes, commit drizzle type files to git. They're generated once and rarely change unless schema updates.
How do I use Drizzle with Vercel Postgres?
Set DATABASE_URL to your Vercel connection string, use dialect: 'postgresql', and ensure migrations are applied on deploy.
