Hi,
This thread may help
And did you try :
yunohost app setting calibreweb do_not_backup_data -v 1 (or 0 I guess ?)

hello @krakinou my yunohost is up to date (yuno : 12.0.17 and calibreweb Version installée : 0.96.24~ynh3) and i have the error above

In the meantime, the workaround from my previous post still stand.
