Custom Requests not working

[springjben]

exchangeAPI.sendCustomRequest('https://bittrex.com/api/v1.1/account/getorder&uuid=deee432e-aa4f-4ff3-81b7-8c1c5e0876c2', function(data, err) {
        console.log(data)
        console.log(err)
        //resolve(data);

      }, true );

It always returns null. The error was: 'Bad Request'

message: 'URL request error'
