I am trying to send an integer via response.send() but I keep getting this error

express deprecated res.send(status): Use res.sendStatus(status) instead

I am not sending a Status, my code is

app.get('/runSyncTest' , function(request, response){  



var nodes = request.query.nodes;

var edges = request.query.edges;

if (edges ==  ){

    edges = []

}



userStory.userStory(nodes,edges);

connection.query('SELECT MAX(id) as id FROM report ', function(err,results, fields) {

                idTest = results[0].id

                response.send (idTest)

});



});
