'unplugin-vue-i18n/messages' is imported by nuxt/dist/server but could not be resolved – treating it as an external dependency.

Reporting a bug?

Could not resolve import
"@intlify/unplugin-vue-i18n/messages" in ...nuxt/dist/server/server.mjs
using exports defined in /node_modules/@intlify/unplugin-vue-i18n/package.json.
'@intlify/unplugin-vue-i18n/messages' is imported by .nuxt/dist/server/server.mjs, but could not be resolved – treating it as an external dependency.

Expected behavior

In dev mode @intlify/unplugin-vue-i18n/messages the package automatically imports the messages created in the locales folder, but while building a ssr in nuxt 3 the builder couldn't resolve the messages file, and treating it as an external dependency.
I was expecting that the builder would import @intlify/unplugin-vue-i18n/messages, so I can find the messages in built ssr file.

Reproduction

Link to github repo that show how i implement it. to see the bug just uncomment this lineGitHub

my bad I haven't properly configured the build transpiler.
build: { transpile: ["@intlify/unplugin-vue-i18n"], },
now it generates perfectly using the code above.
