Help with rclone sync and exclude

What is the problem you are having with rclone?

I am trying to sync an ext4 file system on a RAID1 array with pcloud using rclone.
From an older test and recovery session, there has been left a folder named lost+found that I do not want to sync. The problem with this is that I cannot delete it because it has the immutable flag (i) and I cannot change that with chattr.
I use this command to test if everything is OK:
$ rclone sync /mnt/raid1 remote: -v -i -n --exclude /mnt/raid1/lost+found/
however, I get this:
2025/07/04 15:51:10 ERROR : lost+found: failed to open directory "lost+found": open /mnt/raid1/lost+found: permission denied
How can I get rid of this error?
