For me this error only occures when "Verify ACL access when listing files" on external storage is active. (External SMB Server in this case is 2012R2)

See forum post: https://help.nextcloud.com/t/undefined-offset-1-at-var-www-nextcloud-apps-files-external-lib-lib-storage-smb-php-219/91075

The actual error line moves with different nextcloud versions and patchlevels.

With 20.0.11 it is at line 222: Error: Undefined offset: 1 at /var/www/nextcloud/apps/files_external/lib/Lib/Storage/SMB.php#222

Thank you for this information, I disabled "Verify ACL access when listing files" and now files:scan is working again. After a reboot the error message is gone.
