How to trigger build from JavaScript (REST API) Follow

Hello,

I'm trying to trigger a build from JavaScript. When I try the following code, I get "400 (Bad Request)"

            var data = {
                buildType: {id: buildTypeId}
            }

            console.info(data);
               
            $.ajax({
                method:"POST",
                url:buildQueueUrl,
                data:data,
                dataType: "json",
                contentType: "application/json",
                success: function(){console.log(data);}
            });

Am I doing something wrong? "buildQueueUrl" has the value of "/httpAuth/app/rest/buildQueue"
