Failed to get fileinfo for /AmazonS3/

,

Hi, I just configured Backblaze on Nextcloud but when I send any file it shows this error: “Failed to get fileinfo for /AmazonS3/”.
It may be possible for me to create normal folders, but not for sending. I saw that there is that too. “smbclient” is not installed. Mounting “SMB/CIFS”, “SMB/CIFS using OC login” is not possible. Ask your administrator to install it.

nextcloud installation via snap ubuntu 22.04
