FireStore Client Functions are not responding

[Adeel-Intizar]

Hi, My Code in production was working find but suddenly, firestore functions like get, set etc. have stopped responding and system goes in Not Responding State, the Collection and Document reference of Firebase DB is correct, there is no issues there

Environment details

• OS type and version: Windows 10
• Python version: Python 3.10.0
• pip version: pip 21.2.3
• google-cloud-firestore version: Name: google-cloud-firestore Version: 2.18.0 Summary: Google Cloud Firestore API client library Home-page: https://github.com/googleapis/python-firestore Author: Google LLC Author-email: googleapis-packages@google.com License: Apache 2.0 Location: c:\python\lib\site-packages Requires: google-auth, protobuf, google-cloud-core, google-api-core, proto-plus Required-by: firebase-admin

Code example

# example

cred = credentials.Certificate("secret-key.json")
app = firebase_admin.initialize_app(cred)
store = firestore.client()

login = auth.sign_in_with_email_and_password(email, password)
doc_ref = store.collection('schools').document(login['localId'])

try:
    doc = doc_ref.get()

    if doc.exists:
        data = doc.to_dict()
        print(f"Document Data: {data}")
    else:
        print("No Such Document")
except Exception as e:
    print(f"An Error Occurred: {e}")

The above code doesn't return anything, just goes into not responding state, kind of infinite loop i guess

please help me if I am doing something wrong here, or how can i overcome this issue, i need it to work ASAP, Thank you
