Should there be a guard in case if Python build does no include sqlite3? There is one here:

jupyter_server/jupyter_server/services/sessions/sessionmanager.py

Lines 13 to 17 in f37967b

try:
import sqlite3
except ImportError:
# fallback on pysqlite2 if Python was build without sqlite
from pysqlite2 import dbapi2 as sqlite3 # type:ignore[no-redef]

Good catch, I also saw that these attributes were only introduced in python 3.11, so I've made this check a bit more robust, with a string based comparison as fallback
