Rerro context_processors in django

dictionary update sequence element #0 has length 0; 2 is required

I have a module called context_processors that when enabled does not appear on the login page and gives an error But when I disable it, the login page appears

context_processors.py:

import datetime

from django.contrib.auth.decorators import login_required

from permission.models import UserPermission
from salemali.models import Salemali
from term.models import Term
from user.models import Branch


@login_required
def date_context_processor(request):
    if request.user.is_authenticated:
        current_datetime = datetime.datetime.now()
        term = Term.objects.filter(status=1).order_by('-datestart')
        salemali = Salemali.objects.all()
        branch = Branch.objects.all()
        user_permissions = UserPermission.objects.filter(user=request.user).values_list('permission__name', flat=True)

        return {
            'current_day': current_datetime,
            'terms': term,
            'salemali': salemali,
            'branch': branch,
            'user_permissions': user_permissions
        }

setting.py:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [BASE_DIR / 'templates'],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
                'dashboard.context_processors.date_context_processor',
            ],
        },
    },
]
