Reproduction

Steps to reproduce:

Install and configure the Nuxt i18n module with version 9.0.0.
Run the Nuxt project in development mode (npm run dev or yarn dev).
Open the browser DevTools and attempt to debug the Nuxt i18n code.
Sourcemaps are not loaded, and the original source code is not available for debugging.

Describe the bug

Since upgrading to version 9.0.0 of the Nuxt i18n module, sourcemaps are no longer being loaded, preventing me from debugging the code in the browser. This issue makes it difficult to trace and debug the source code using browser DevTools.

More info

Why do I need to provide a reproduction?

Reproductions make it possible for us to triage and fix issues quickly with a relatively small team. It helps us discover the source of the problem, and also can reveal assumptions you or we might be making.

What will happen?

If you've provided a reproduction, we'll remove the label and try to reproduce the issue. If we can, we'll mark it as a bug and prioritise it based on its severity and how many people we think it might affect.

If needs reproduction labeled issues don't receive any substantial activity (e.g., new comments featuring a reproduction link), we'll close them. That's not because we don't care! At any point, feel free to comment with a reproduction and we'll reopen it.

How can I create a reproduction?

We have a couple of templates for starting with a minimal reproduction:

👉 Reproduction starter (v8 and higher)
👉 Reproduction starter (edge)

A public GitHub repository is also perfect. 👌

Please ensure that the reproduction is as minimal as possible. See more details in our guide.

I'm also facing this same issue

Here's is a reproduction https://codesandbox.io/p/devbox/funny-rgb-hj2thz?workspaceId=649ba03f-26ca-46d1-89e9-81b5aa2c40d0

As you can see in .output/public/_nuxt, all the sourcemaps are invalid as they don't present any value in sources and mappings are empty
