Cloudrun Django+Terraform / 404 error on app URL - django

Question

I just followed this tutorial : https://github.com/GoogleCloudPlatform/serverless-expeditions/tree/main/cloud-run-django-terraform
I've done :
gcloud builds submit --config cloudbuild-migrate.yaml
terraform apply -var project=$PROJECT_ID
My database was created. Service was pushed online well and I've got a service_url.
When I access it, it shows a 404 error. Even if try to access the /admin page, it just returns a 500 error with no explanation in the log journal (or I didn't find it).
When I try to runserver on localhost with sql_cloud_proxy, Django works perfectly. It's just a Django basic project showing hello on homepage.
I don't get it.
Here's my settings.py file :
import io
import os
from pathlib import Path
import environ
import google.auth
from google.cloud import secretmanager
BASE_DIR = Path(__file__).resolve().parent.parent
env = environ.Env(DEBUG=(bool, False))
env_file = os.path.join(BASE_DIR, ".env")
# Attempt to load the Project ID into the environment, safely failing on error.
try:
_, os.environ["GOOGLE_CLOUD_PROJECT"] = google.auth.default()
except google.auth.exceptions.DefaultCredentialsError:
pass
if os.path.isfile(env_file):
# Use a local secret file, if provided
env.read_env(env_file)
elif os.environ.get("GOOGLE_CLOUD_PROJECT", None):
# Pull secrets from Secret Manager
project_id = os.environ.get("GOOGLE_CLOUD_PROJECT")
client = secretmanager.SecretManagerServiceClient()
settings_name = os.environ.get("SETTINGS_NAME", "django_settings")
name = f"projects/{project_id}/secrets/{settings_name}/versions/latest"
payload = client.access_secret_version(name=name).payload.data.decode("UTF-8")
env.read_env(io.StringIO(payload))

CMD exec gunicorn --bind 0.0.0.0:$PORT --workers 1 --threads 8 --timeout 0 myapp.wsgi:application
I've tried to set DEBUG=True to show something but nothing changed.
Is someone has an idea to fix this issue ?
Many thanks,
