External storage with smb, file notify failed

Hi community,
I have installed last version. then add a external smb storage .Adding permissions to users
the config like below, and then I create the folder and add permissions to user “user1” on windows server share/user1


After that config, but when I uploaded a file

Then I try to use commond to notify ,

These problems are due to the use of the $user case.
Is there any way to solve this problem?

ENV:
Nextcloud Hub 8 (29.0.6)
External Storage 1.21.0
LDAP
OS: ubuntu 22.04

deploy with source code

Please see the note here about using with save in session: https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/external_storage/smb.html#smb-authentication
