Google Cloud Functions Webhook with PyWA

[ecnjava]

Hi guys!!
I'm using GCF webhook and PyWA....
Throughout GC Logs explorer, I can see the incoming messages accordingly, but my Flask server is not being triggered whenever a message arrives (@wa_ret.on_message(filters.command("start")))..... Could you please advise me???

Here is my source code:

import flask # pip3 install flask
from pywa import WhatsApp, types

flask_app = flask.Flask(name)

async def init_wa():
global wa_ret
if wa_ret is None:
wa_ret = WhatsApp(
phone_id="3",
server=flask_app,
token="1",
verify_token='1',
api_version=21.0,
continue_handling=True)

    @wa_ret.on_message(filters.command("start"))
    async def on_start(_: WhatsApp, m: Message):
        await m.reply("Who are you?")

@https_fn.on_request()
def webhook(request: https_fn.Request) -> https_fn.Response:
if request.method == 'GET':
mode = request.args.get('hub.mode')
token = request.args.get('hub.verify_token')
challenge = request.args.get('hub.challenge')
challenge_200 = challenge, 200

    if mode and token:
        if mode == 'subscribe' and token == '1':
            return challenge_200
        else:
            return 'Invalid verification token', 403
    else:
        return 'Missing parameters', 400

elif request.method == 'POST':
    if wa_ret is None:
        asyncio.run(main())  # Initialize WhatsApp if not done

return jsonify({'status': 'success'})
