I’m trying to find some easy setup to send trades from TradingView’s alerts into Interactive Brokers. I have set up a local host, I have ngrok running, and I have created the code below by watching some YTB video. I have also added the URL for webhook in the alerts in Trading View. The problem is that every time there is an alert, I get a 500 internal server error message in ngrok. And the trades do not execute.

**This is the code I’ve tried:
**

`#imports
from datetime import datetime
from sanic import Sanic
from sanic import response
from ib_insync import *

#Create Sanic object called qpp
app = Sanic(__name__)
#app.ib = None
app.ctx.ib = None

#Create root / homepage
@app.route('/')
async def root(request):
return response.text('online')

#Listen for signals and submit BUY orders (webhook)
@app.route('/buy', methods=[ 'POST' ]) 
async def buy(request):
if request.method == 'POST':
#Check if we need to reconnect
await checkIfReconnect()
#Parse signal data
data = request.jason
order = MarketOrder('BUY', 0.00015)
contract = Crypto('BTC', 'PAXOS', 'USD')
trade = app.ib.placeOrder(contract,order)
#Wait for the order to be processed and check status
app.ctx.ib.sleep(1)
print(trade)

#Listen for signals and submit SELL orders (webhook)
@app.route('/sell', methods=[ 'POST' ]) 
async def sell(request):
if request.method == 'POST':
#Check if we need to reconnect
await checkIfReconnect()
#Parse signal data
data = request.jason
order = MarketOrder('SELL', 0.00015)
contract = Crypto('BTC', 'PAXOS', 'USD')
trade = app.ib.placeOrder(contract,order)
#Wait for the order to be processed and check status
app.ctx.ib.sleep(1)
print(trade)

#Reconnect to IB if connection is lost
async def checkIfReconnect():
if not app.ib.isDisconnected() or not app.ib.isConnected():
app.ib.disconnect()
app.ib = IB()
app.ib.connect('127.0.0.1',7496,clientId=1)

#Run app
if _name_ == '__main__':
#Connect to IB
app.ctx.ib = IB()
app.ctx.ib.connect('127.0.0.1',7496,clientId=1)
app.run(port=8080)`

**This is the error I get:
**
{
“description”: “Internal Server Error”,
“status”: 500,
“message”: “The application encountered an unexpected error and could not continue.”
}

**I also see these errors in the Terminal:
**
