Errors

NUXT_AUTH_UNSUPPORTED_DIALECT: Unsupported database dialect

Select sqlite, postgresql, or mysql for NuxtHub auth schema generation.

Example error

[NUXT_AUTH_UNSUPPORTED_DIALECT] Unsupported database dialect: postgres

Why this happens

NuxtHub schema generation received a missing or unsupported dialect. For example, the NuxtHub dialect is postgresql, even though some database adapters use the shorter name pg.

How to fix it

Configure hub.db with a supported dialect: sqlite, postgresql, or mysql.

Use the NuxtHub dialect name in hub.db:

nuxt.config.ts

export default defineNuxtConfig({
  hub: { db: { dialect: 'postgresql' } },
})

The other supported values are sqlite and mysql. This option describes the schema dialect; it does not replace the connection configuration required by your database.

Verify the fix

Run pnpm exec nuxt prepare and check for a generated schema matching the configured dialect.
