I have the following main.py firebase function which I am trying to deploy using firebase deploy But when I curl the firebase endpoint I get a 404 error:
curl -v https://us-central1-<project-id>.cloudfunctions.net/test
Here is the function I deployed:
from firebase_admin import initialize_app, db
from firebase_functions import https_fn
import flask
initialize_app()
app = flask.Flask(__name__)
print("TEST APP")
@app.get('/test')
def hello_world():
print('Hello World')
return 'Hello, Firebase Cloud Functions with Python'
When I run the function locally by entering this command flask --app main run I am able to hit this endpoint, but not when I curl the firebase endpoint. Any help is appreciated.
Updated: When I go to the Google Cloud Console, no functions appear. I am thinking that there must be a problem with the deployment. When I type: firebase -P staging deploy --only functions
I get the following output:
(node:25815) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.

I found what I was missing to get the firebase cloud function working using python's Flask library. I had to register the flask app to use https_fn wrapper. Here is the code which now works when doing a firebase deploy
import firebase_admin
from firebase_admin import credentials, firestore
from flask import Flask, request
from firebase_functions import https_fn
from cancer import get_cancer
# Initialize Firebase Admin SDK
cred = credentials.Certificate("serviceAccountKey.json")
firebase_admin.initialize_app(cred)
db = firestore.client()
app = Flask(__name__)
@app.route('/test', methods=['GET'])
def test():
print("Hello World")
return "Hello World"
# Main entry point for Firebase Functions
#firebase_function = functions.https.on_request(app)
@https_fn.on_request()
def functions(req: https_fn.Request) -> https_fn.Response:
with app.request_context(req.environ):
return app.full_dispatch_request()
You can find more documentaiton in the following firebase docs:
https://firebase.google.com/docs/functions/http-events?gen=2nd
You can then access the test endpoint by going to curl -v https://us-central1-<project-id>.cloudfunctions.net/functions/test
