Doesn't work on Cockpit 8.11

[yusufiga]

Hi, First of all, thanks for the great addon. It looks great but unfortunately, it doesn't work. When I try to use it, loading is never ending and I seePOST https://domain.com/cockpit/backup-and-restore/find {error: "500", message: "system error"} in the console logs. I tried to see any error log in the server but couldn't find anything. Could you please check if plugin still(or with version 8.11) works?

My Cockpit version is 8.11

Thanks, kind regards

composer install should fix this
