Datastore emulator causes firebase admin to hang

Commencez par exécuter les commandes de l’émulateur datastore du rapport ainsi que le script Python fourni, en vous concentrant sur la transition de datastore_client.context() vers auth.get_user_by_email(). Comparez le comportement lorsque les trois lignes de contexte datastore sont supprimées. Le travail est considéré comme terminé lorsque la recherche Firebase Auth renvoie normalement alors que l’émulateur datastore est en cours d’exécution, et que le processus reste interruptible.

[REQUIRED] Step 2: Describe your environment

• Operating System version: Mac 14.5
• Firebase Product: firebase-admin==6.2.0 and firebase-admin==6.5.0
• Python version: 3.11.4
• Pip version: 24.0

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

This problem started around June 1. Before, I have been doing this for several years without any issues.

The problem is that auth.get_user_by_email() freezes and it is caused by some interaction with running the cloud datastore emulator locally. This happens with either the older emulator (gcloud beta emulators datastore start) or the newer one (gcloud emulators firestore start ). I have tried downgrading gcloud and two versions of firebase-admin listed above.

Run the script below. At auth.get_user_by_email(), the script hangs indefinitely with no output. You can't even ctrl-c to stop the script. You need to kill -9 in a separate terminal window.

If you comment out the three lines starting with with datastore_client.context():, then auth.get_user_by_email() works.

Since the code just freezes, I am at a loss as to how to debug.

Relevant Code:

import os
from google.cloud import ndb
import firebase_admin
from firebase_admin import auth, initialize_app

print('starting')

class User(ndb.Model):
    email = ndb.StringProperty(required=True)

os.environ['DATASTORE_DATASET'] = 'my-project'
os.environ['DATASTORE_EMULATOR_HOST'] = 'localhost:8081'
os.environ['DATASTORE_EMULATOR_HOST_PATH'] = 'localhost:8081/datastore'
os.environ['DATASTORE_HOST'] = 'http://localhost:8081'
os.environ['DATASTORE_PROJECT_ID']= 'my-project'

datastore_client = ndb.Client('my-project')

if not firebase_admin._apps:
    initialize_app()

email = 'me@example.com'

with datastore_client.context():
    user = User.get_by_id(email)
    print(user)

# This hangs and you can't even ctrl-c to stop.
# Works if datastore client stuff is commented out.
fb_user = auth.get_user_by_email(email)
print(fb_user)
