get_perms returns empty list while get_user_perms returns permissions

[BSVogler]

I wrote a script to give me all objects which don't have enough permissions.
I used shortcuts get_perms to check the permissions for the user and I found some entries because they returned []. But on closer inspection, I can see the obejcts have permissions and they are returned when I use get_user_perms.

Shouldn't get_perms return a superset of get_user_perms?

Here is my script, using guardian 2.4.0

from guardian.shortcuts import get_user_perms, get_perms
from app.models import PreferencesRecord

for pref in tqdm.tqdm(PreferencesRecord.objects.all()):
    perms = get_perms(pref.user, pref)
    if len(perms) < 4:
        print(f"User {pref.user.username} ({pref.user.id}) has {len(perms)} permissions on {pref.id}")
        user_perms = get_user_perms(pref.user, pref)
        if user_perms != perms:
            print(f"But the user permissions return {user_perms}, while perms are {perms}")

Have you have GUARDIAN_AUTO_PREFETCH set to True in your Django settings?

Unless I made a mistake I don't think that it was overwritten to be True.
