Switch screenshot language gives 404 error

Where to find the issue

First noticed with https://www.coronawarn.app/en/screenshots-archive/2-2.html https://www.coronawarn.app/de/screenshots-archive/2-2.html

Reviewed as not yet fixed for screenshot versions (2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9 and 2.10).

Describe the issue

This is a duplicate of the comment in the merged https://github.com/corona-warn-app/cwa-website/pull/1399#issuecomment-863846009 to ensure that the issue is listed in an open item.

Switching languages when viewing screenshots which are not from the latest version does not work on the production server https://www.coronawarn.app although it does work on a local clone http://localhost:8000/ run through npm start.

Repro steps

1. Open https://www.coronawarn.app/en/screenshots/
2. In the Versions drop-down select a version which is not the latest, e.g. 2.8
3. Click DE in header
4. Browser tries to open https://www.coronawarn.app/de/screenshots-archive/2-8 (for instance) and shows 404 error

The same problem occurs when trying to switch from German to English.

I set up a local nginx server and I can reproduce the issue. The web server is looking for an index.html and not finding it.

A possible solution may be to:

• create new directories screenshots-archive/2-2, screenshots-archive/2-3 etc for both languages
• move the 2-2.html, 2-3.html, etc. files to the new folders and rename each of them to index.html
• adjust the stylesheet references due to the move of the files one layer lower
• correct the global.json to refer to directories instead of files

Unfortunately I can’t make these changes myself, because the files I refer to are generated and it would need somebody with javascript skills to sort this out. It’s not such a simple task.

The issue regarding accessing 2.3 screenshots has been resolved with PR https://github.com/corona-warn-app/cwa-website/pull/1440.

The problem when switching languages remains however.
