Saving an image from a URL in Parse.com using CloudCode

Question

I struggled with saving the file that I get from the HTTP request for several days. Here is my code:

Parse.Cloud.httpRequest({ url: "https://ss1.4sqi.net/img/categories_v2/food/vietnamese_88.png", success: function(httpImgFile) { console.log("httpImgFile: " + String(httpImgFile.buffer)); var imgFile = new Parse.File("imgFile1.png", httpImgFile.buffer); object.set("location", "newYork"); //object is a PFObject retrieved earlier object.set("icon1", imgFile); object.save(null, { success: function(gameScore) { response.success("saved object"); }, error: function(gameScore, error) { response.error("failed to save object"); } }); }, error: function(httpResponse) { console.log("unsuccessful http request"); response.error(responseString); } }); 

The error I am getting is:

 Failed with: TypeError: Cannot call method 'then' of undefined at Object.b.File.save (Parse.js:2:14963) at null.<anonymous> (Parse.js:2:30041) at e (Parse.js:2:6339) at Parse.js:2:7092 at g (Parse.js:2:6829) at c.extend.then (Parse.js:2:7077) at Parse.js:2:30016 at Array.forEach (native) at Function.x.each.x.forEach (Parse.js:1:661) at Function.b.Object._deepSaveAsync (Parse.js:2:29993) 

The strangest part of all this is that the error only occurs when I include the line object.set("icon1", imgFile) I can change the location of the object without any problems. The error only occurs when trying to save imgFile to icon1

Any help would be greatly appreciated. Thanks!

According to the documentation ( https://parse.com/docs/js_guide#files ) you need to save the analysis file before you can install it on another object.

Usually:

 imgFile.save().then(function () { ... object.set("icon1", imgFile); return object.save(); }).then(function (gameScore) { response.success("saved object"); }, function (error) { response.error("failed to save object"); }); 

I also rewrote this part of the function to illustrate a sample promise, as it is a little easier when it comes to a series of queries like this.
