+Would you be able to provide a [reproduction](https://nuxt.com/docs/community/reporting-bugs/#create-a-minimal-reproduction)? 🙏
+
+<details>
+<summary>More info</summary>
+
+### 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:
+
+👉 https://stackblitz.com/github/nuxt/starter/tree/v3-stackblitz
+👉 https://codesandbox.io/s/github/nuxt/starter/v3-codesandbox
+
+A public GitHub repository is also perfect. 👌
+
+Please ensure that the reproduction is as **minimal** as possible. See more details [in our guide](https://nuxt.com/docs/community/reporting-bugs/#create-a-minimal-reproduction).
