Would you be able to provide a reproduction? 🙏

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.

After many tries to provide a reproduction, I found the problem

The error occurred because I didn't have

"typescript": "^5.7.2"

in my package.json

The problem doesn't occur with 8.5.5

Reproduction: Codesandbox

I had the same problem. After installing the latest version of @nuxtjs/i18n (9.1.0), I got the error Nuxt module should be a function: [object Object].

After installing typescript^5.7.2, the problem was solved.

While debugging locally all I can figure out is that this issue is specific to yarn (somewhat related nuxt/nuxt#22861, see logs in the last comment).

Unfortunately #3251 has failing CI, I'll see if I can update deps and resolve it locally but I can imagine this issue will pop up again (when fixed) later as it seems to be something to do with dependency resolution.
