Errors

NUXT_AUTH_EMPTY_SCHEMA: Schema generator returned no code

Check Better Auth database options and plugins when schema generation returns an empty result.

Example error

[NUXT_AUTH_EMPTY_SCHEMA] Schema generation returned empty result for sqlite

Why this happens

Better Auth's Drizzle schema generator returned an empty result for the selected dialect. There is no schema code for the module to write, so setup stops.

How to fix it

Check the Better Auth plugins and database options in defineServerAuth(), then regenerate the schema.

Check recent changes to defineServerAuth(), especially plugin schema definitions and database options. In a development branch, isolate plugin configuration changes and rerun preparation after each change:

pnpm exec nuxt prepare

If a minimal config still returns no code, report the diagnostic code, dialect, Better Auth version, and a minimal reproduction. Preserve the last working schema while investigating.

Verify the fix

Preparation should produce a non-empty schema with the auth tables expected for your configuration. Review the generated code before applying migrations.
