i18n zh-CN show 404 not found

[CN059]

I use npx create-docus my-docs -t i18n to create a project.
and I set zh-CN as the default language in this project,like this(nuxt.config.ts):

export default defineNuxtConfig({
  extends: ["docus"],
  modules: ["@nuxtjs/i18n"],
  i18n: {
    defaultLocale: "zh-CN",
    locales: [
      {
        code: "zh-CN",
        name: "简体中文",
      },
      {
        code: "en",
        name: "English",
      },
      {
        code: "fr",
        name: "Français",
      },
    ],
  },
});

zh-CN folder I had created:

this is the router's message:

[CN059]

Is this due to issues with special characters and uppercase letters?

[CN059]

exist a little question,I use bun package manager

[Whbbit1999]

The generated SQLite file contains the name zh_CN; I wonder if this is related.

[CN059]

Is your deployment working properly?

The generated SQLite file contains the name zh_CN; I wonder if this is related.生成的 SQLite 文件包含名称 zh_CN；我想知道这是否与此有关。

[Whbbit1999]

It is not working.

[CN059]

Things have gotten a bit tricky.

[Whbbit1999]

The simplest solution is to rename i18n/locales/zh-CN.json to i18n/locales/cn.json. However, after the change, it no longer conforms to geographic identifier codes such as zh-cn, zh-tw, zh-hk, etc.

[larbish]

Could it be related to: #1254 ?

[CN059]

I will try.
