javascript - parse.com "error: unauthorized" when trying to save object -

i using masterkey yet still getting unauthorized error when trying save object. can figure out why? can see "started making ticket" gets logged. , request.params pull correct information.

also, side question...i under impression if response.error executed stops code, send error message function called cloud code , run error handling there. have console.log error message in cloud code, , error alert in function called it. getting console log show, not alert. assumption wrong in doesnt passed, , terminates entire thing upon executing response.error?

parse.cloud.define("createrecord", function(request, response) {     var caseclass = parse.object.extend("cases");     var ticket = new caseclass();     console.log("started making ticket");     ticket.title = request.params.title;     ticket.category = request.params.category;     ticket.priority = request.params.priority;     ticket.description = request.params.cmnts;     ticket.save(null, {usemasterkey: true}).then(function() {         response.success();     }, function(error) {         response.error("error response: " + error.message);     }); 

try this:

parse.cloud.run("createrecord", {something: yourdata}, {... 

and:

parse.cloud.define("createrecord", function (request, response) {     var = request.params.something;     var caseclass = parse.object.extend("cases");     var ticket = new caseclass();     console.log("started making ticket");     ticket.set("title", something.title);     ticket.set("category", something.category);     ticket.set("priority", something.priority);     ticket.set("description", something.cmnts);     ticket.save(null, {usemasterkey: true}).then(function() {         response.success();     }, function(error) {         response.error("error response: " + error.message); });
