How to Fix Supabase TypeScript Types Wrong in AI-Built Apps
Generated Supabase TypeScript types don't match the actual database schema. AI tools use outdated or manually written types instead of generating them from the live database.
Error messages you might see
Type '{ name: string; }' is not assignable to type 'TablesInsert<"users">'Property 'email' does not exist on type 'Tables<"profiles">'Why this happens in AI-generated code
Types not regenerated after schema changes
Database columns were added or modified but `supabase gen types` wasn't re-run.
Manually written types
AI writes type definitions by hand instead of generating them, leading to drift from the actual schema.
Wrong database URL for generation
Types were generated from a different environment (local vs production) with a different schema.
How to fix it
Regenerate types from the database
Run `supabase gen types typescript --project-id your-project-id > src/types/database.ts` after every schema change.
Add type generation to CI
Include type generation in your build pipeline so types are always in sync with the latest schema.

Frequently asked questions
How do I use generated types with the Supabase client?
Pass the generated Database type as a generic: `createClient<Database>(url, key)`. This types all queries automatically.
Can I extend the generated types?
Yes. Create a separate file that imports and extends the generated types. Never edit the generated file directly.
