Lose the content after moving a number of folders in Amazon S3 External storages

Losing the content after moving a number of folders from source folder to destination folder in Amazon S3 External storages.

Actually, i original need to rename a folder(a complex hierarchy inside, may be it is a problem), it does not have any error message, but the result as: i see the new name folder, but it is no content inside.

Then i still can see the old folder, i went into it, and manually move the content folders into new name folder, it ran for a while, then comes out some error messages as “fault moving”, then i checked back the older folder, the folders hierarchy are still there, but the files inside each folder are lost.

I checked the new folder and its hierarchy, it is missing too.

Nextcloud version : 16.0.4
Operating system and version (eg, Ubuntu 17.04): https://github.com/nextcloud/docker tags/16.0.0-fpm-alpine

Is this the first time you’ve seen this error? Y
