A fresh install on debian 13, then restore config and data

This is the error we get :

dovecot: sieve(name@domaine.tld)<16329><mBy5ACZXnsB/AAAB>: Error: sieve: file storage: Sieve storage path '/var/vmail/vmail1/domaine.tld/n/a/m/name-
2021.04.15.10.29.46//sieve/dovecot.sieve' is not a directory, but it is to be opened for write access 

To solve this problem we had to change dovecot.conf from this :

sieve_script personal {
    type = personal
    driver = file
    path = ~/sieve/dovecot.sieve
}

to this :

sieve_script personal {
    type = personal
    driver = file
    path = ~/sieve
    active_path = ~/sieve/dovecot.sieve
}

It's the second server on debian 13 that has this issue.

Is this normal ? did I find a bug ?
