CORS Error? FastAPI + FastAPI-SocketIO

[BuckLearnsCode]

I'm hitting a 403 locally. Been trying to debug for days.

from flask_socketio import SocketIO
from flask_cors import CORS
from fastapi import FastAPI, WebSocket, Depends
from fastapi_socketio import SocketManager
from fastapi.middleware.cors import CORSMiddleware
from fastapi.staticfiles import StaticFiles
from fastapi.responses import FileResponse

app = FastAPI()
app.mount("/static", StaticFiles(directory="front/build", html=True), name="static")

socket_manager = SocketManager(app=app)

Set CORS

origins = [
"http://localhost:3000"
]

app.add_middleware(
CORSMiddleware,
allow_origins=origins,
allow_credentials=True,
allow_methods=[""],
allow_headers=[""],
)

GAME_NAMESPACE = "/game"

if name == "main":
# LOCAL
port = int(os.environ.get("PORT", 5001))
import uvicorn
uvicorn.run(app, host="127.0.0.1", port=port, log_level="info")

On Client:
const SERVER_URL = 'http://127.0.0.1:5001';
const GAME_NAMESPACE = '/game';

To run locally I'm using:
uvicorn server:app --reload --port 5001.

ERRORS:
WebSocket connection to 'ws://127.0.0.1:5001/socket.io/?EIO=4&transport=websocket' failed
INFO: ('127.0.0.1', 51879) - "WebSocket /socket.io/?EIO=4&transport=websocket" 403
INFO: connection failed (403 Forbidden)
INFO: connection closed

Any ideas?
