fix: sitemap is empty with Content v3

[HADB]

🐛 The bug

Hi!

I’m currently migrating my project to Nuxt Content v3, and I’ve encountered an issue with @nuxtjs/sitemap version 7.2.1.

The /__sitemap__/posts.xml and /__sitemap__/pages.xml in my project are empty.

After debugging, I found that /__sitemap__/nuxt-content-urls.json returns an empty array. Further logs revealed that the sitemap property in the result of queryCollection is null for every item. However, I’m not sure how to proceed with pinpointing the issue.

Below are my configs:

nuxt.config.ts：

  sitemap: {
    sitemaps: {
      pages: {
        includeAppSources: true,
        exclude: [
          '/posts/**',
          '/tags/**',
          '/test',
        ],
      },
      posts: {
        includeAppSources: true,
        include: [
          '/posts/**',
        ],
      },
      tags: {
        sources: [
          '/api/__sitemap__/tags',
        ],
      },
    },
  },

content.config.ts：

import { defineCollection, defineContentConfig, z } from '@nuxt/content'
import { asSitemapCollection } from '@nuxtjs/sitemap/content'

export default defineContentConfig({
  collections: {
    pages: defineCollection(
      asSitemapCollection({
        type: 'page',
        source: '*.md',
        schema: z.object({
          hideComments: z.boolean().optional(),
        }),
      }),
    ),
    posts: defineCollection(
      asSitemapCollection({
        type: 'page',
        source: 'posts/*.md',
        schema: z.object({
          class: z.string().optional(),
          cover: z.string().optional(),
          coverSize: z.object({ width: z.number(), height: z.number() }).optional(),
          date: z.string(),
          draft: z.boolean().optional(),
          hideComments: z.boolean().optional(),
          readingTime: z.object({}),
          tags: z.array(z.string()),
          time: z.string().optional(),
        }),
      }),
    ),
  },
})

Hi, thanks for the issue. This looks like an issue with the Nuxt Content hooks running before the sitemap module loads. A work around for the time being is to load @nuxt/content last in your modules.

I'll push up a console warning for this use case but I'll need Nuxt Content to fix this upstream.
