Short sale error

I am trying to do a short sale and running into issue.

This is my order request
{“side”:“sell”,“symbol”:“AAPL”,“qty”:1,“time_in_force”:“gtc”,“order_class”:“bracket”,“take_profit”:{“limit_price”:226.51},“stop_loss”:{“stop_price”:229.98},“type”:“limit”,“limit_price”:230.01}

I keep getting a 422

Please help
