Error': 'InternalServerError' when trying to place an order

[berbaroovez]

client = a.easy_client("secret-id", "secret-stuff", "http://localhost:3001/callback")

placed_order = client.place_order(
{
"AccountID": "SIM232secret",
"Symbol": "HMST",
"Quantity": "1",
"OrderType": "Market",
"TradeAction": "Buy",
"TimeInForce": {
"Duration": "GTC"
},
"Route": "Intelligent"
}
)

When making the following call im getting an error about internal server error. I can make the same call in a postman request no problem. Any clue whats going on ?
