Full backup feature not working

[damienbfs]

Describe the bug
The full backup feature redirects to https://umap.osm.ch/map/null/download/, which results in a 404 not found error. The link to share the map is https://umap.osm.ch/en/map/, which does not allow to recover it.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'http://link-to-your-map' (⚠️ VERY IMPORTANT, we need to know which instance of uMap is concerned! Your issue will probably be ignored without that link) -> The link to my map is only https://umap.osm.ch/en/map/, which does not allow to recover it.
2. Click on 'Share and download' then 'full_backup'
3. This redirects to https://umap.osm.ch/map/null/download/

Expected behavior
The 'full_backup' button should redirect to a download page for a .umap file.

Desktop (please complete the following information):

• OS: Windows 11
• Browser Firefox
• Version 135.0

It happens if the map hasn't been saved yet. I think we should hide the link in that case.

Hi @davidbgk,

Thanks a lot, that makes sense.

I was certain I had tried that already, seems like I did not... Sorry for the inconvenience.
