[Python] emit Broadcast with flask_socketio

I have a flask server running, and sockets are connection successfully. I want to run a service that monitors stuff on my server, such as GPU usage with GPUMonitorService, and the broadcast that data to all connected sockets. I make the GPU service, and pass in the socketio object. I have an on.connect handler that works as expected. I used these docs for reference https://flask-socketio.readthedocs.io/en/latest/getting_started.html#broadcasting

from flask import Flask, request, jsonify, send_file
from flask_socketio import SocketIO

from services.GPU_Monit import GPUMonitorService

socketio = SocketIO(...)

gpu_service = GPUMonitorService(socketio)

@socketio.on("connect")
def handle_connect():
client_id = request.sid # Get the unique socket ID of the client
print(f"Client connected: {client_id}")
# Emit the new client's ID to all connected clients
socketio.emit( # <---this is working
"new_connection",
{"socket_id": client_id},
)


//GPU_Monit.py

from flask_socketio import emit

class GPUMonitorService:
def __init__(self, socketio):
self.socketio = socketio
self.thread = threading.Thread(target=self._monitoring_task, daemon=True)
self.thread.start()

def _monitoring_task(self):
while True:
try:
gpu_info = self.get_detailed_gpu_info()
if gpu_info:
#This line does run, but the connected sockets are not getting any messages
emit("gpu_update", gpu_info, broadcast=True)
except Exception as e:
print(f"Error in GPU monitoring: {e}")
time.sleep(10)


Any thoughts would be appreciated. I'm more familiar with sockets on NodeJS, and Python has some weird things with threads and special async handling that I'm not aware of. Thanks!

EDIT: Im getting an error 'Working outside of request context.This typically means that you attempted to use functionality that needed an active HTTP request. Consult the documentation on testing for information about how to avoid this problem.'
