Errors

NUXT_AUTH_MISSING_HUB_DB: NuxtHub database alias is missing

Configure NuxtHub before Nuxt Better Auth so the hub:db alias is available.

Example error

[NUXT_AUTH_MISSING_HUB_DB] hub:db not found.

Why this happens

The module selected the NuxtHub database provider, but NuxtHub had not registered the hub:db alias. Check module order, hub.db, and any custom provider hooks that force the nuxthub provider.

How to fix it

Load @nuxthub/core before @nuxtjs/better-auth and configure hub.db.

Configure NuxtHub before the auth module:

nuxt.config.ts

export default defineNuxtConfig({
  modules: ['@nuxthub/core', '@nuxtjs/better-auth'],
  hub: { db: 'sqlite' },
})

Install @nuxthub/core if it is missing. If you use a separate database adapter, remove any hook that forces selection of the NuxtHub provider.

Verify the fix

Run pnpm exec nuxt prepare. NuxtHub should register hub:db and the auth module should generate its schema.
