[REQUIRED] Step 2: Describe your environment
- Operating System version: Windows 10
- Firebase SDK version: 12.4.2
- Firebase Product: firestore (auth, database, storage, etc)
- Python version: 3.10.13
- Pip version: 23.2.1
[REQUIRED] Step 3: Describe the problem
I'm dealing with a Python+Emulator problem. My emulator works in Flutter, but not in Python, and it works in Python on Cloud Firestore. It's only the Python+Emulator combo that is giving me trouble.
It was working earlier today, but so far my backtracking attempts have been unsuccessful.
I've tried restarting my machine, and the emulator, but neither have worked so far.
Steps to reproduce:
What happened? How can we make the problem occur?
This could be a description, log/console output, etc.

Also, this comes out of one of the emulator processes (unsure which):
Oct 07, 2023 8:54:35 PM io.gapi.emulators.netty.HttpVersionRoutingHandler channelRead
INFO: Detected non-HTTP/2 connection.
Relevant Code:
My .env:
FIRESTORE_EMULATOR_HOST=http://localhost:8080
STORAGE_EMULATOR_HOST=http://localhost:9199
When I remove http:// from the variables, I get instead that no connection adapters are available.
import firebase_admin
def initialize_firestore():
app = firebase_admin.initialize_app()
db = firestore.client()
return app, db
if __name__ == "__main__":
callback_done = threading.Event()
app, db =initialize_firestore()
doc_ref = db.collection('files').where(
filter=FieldFilter('extractedText', '==', ''))
print(doc_ref.get())
print('Statement complete')
Code hangs on the second-to-last statement. It works fine on Google Cloud, it's only on emulator that it doesn't work, which is why I'm posting here.
