Static 404 errors in different languages.

[chiqui3d]

Although I see well that you force to always generate 404.html statically, sometimes as in my case I need it to be dynamic because the content depends on the language, do you know any way to do it easily?

Another thing, I have realized that it is generating two 404.html files, one in the out root and another in the out/404/404.html folder, do you know what is due?

Hi, you can use a _error.js file in your pages folder, and depends on how you set the language env variables, change the language accordingly.

Using _error is discouraged for 404.

If you need dynamic content you can fetch the dynamic content client-side.

My approach to this will likely be to render the 404 page (pages/404.js) multiple times with different query params, and place them into different locations during static export (/en/404.html, /de/404.html, …)
