Can't restore Wallabag backups

What type of hardware are you using: Raspberry Pi 3, 4+
What YunoHost version are you running: YunoHost 12.0.7 (stable)
What app is this about: Wallabag

Describe your issue

Hi,

I installed the latest Yunohost on my new Pi 5 (upgrade from a Pi 3B).

Everything went fine and it is is running smoothly. I restored most of my applications from backups I made when using the Pi 3B.

However I can’t restore Wallabag.

Full log is here: https://paste.yunohost.org/raw/kufopuzaqu

I use the backup file created and downloaded in the Pi 3B, so it is only a .tar file (the .json file is inside it).

Thank you for any help.

As I can’t restore my backup, do you know if there is a way to find the URLs saved by my Wallabag, in the backup .tar backup archive?

Thank you.
