Promise with @grant doesn't work on Safari

[ccloli]

// ==UserScript==
// @name         Promise test
// @namespace    http://tampermonkey.net/
// @version      0.1
// @description  try to take over the world!
// @author       You
// @include      *
// @grant        GM_xmlhttpRequest

// ==/UserScript==

(function() {
    'use strict';
    
    Promise.resolve('Success').then(function(value) {
        console.log(value); // "Success"
    }, function(value) {
        console.log('??????');
    });
})();

In Chrome with Tampermonkey Beta v4.3.5421 it works fine, Success will be shown in console. And if the @grant is none, Safari will also show it. But when use specific @grant like GM_xmlhttpRequest, it will throw TypeError in Safari.

System: macOS Sierra (10.12.4)
Browser: Safari 10.1 (12603.1.30.0.34)
Extension: Tampermonkey v4.3.5421

Now temporary fixed with

if (!Promise || !Promise.resolve) {
	var Promise = unsafeWindow.Promise;
}

Anyway Promise is in standard ECMAScript, it shouldn't be blocked in sandbox, and it works fine in other browsers.

Sorry for the delay. Should be fixed now: http://tampermonkey.net/changelog.php?version=4.3.5437&ext=G3XV

Hii, I'm still having the problem with Safari Browser.

i have the below code

// @grant        GM_xmlhttpRequest

GM_xmlhttpRequest({
            method: 'GET',
            url: url,
            responseType: 'json',
            onload: function (responseCurrentUser) {})

This works very fine in crome and firefox box in safari it gives this error...

response: Object

error: "Unauthorized"

error_description: ""

Object Prototype

responseHeaders: "access-control-expose-headers: Location
↵cache-control: no-cache, no-store, no-transform, must-revalidate
↵content-encoding: UTF-8…"

responseText: 

responseType: "json"

responseXML: 

status: 401

statusText: ""

The same code is working well for chrome and firefox.

I don't understand why? I tried to google it but not found answer.. so could you please tell me where I'm wrong? or what I'm missing?

I also had a look here, but no found the reason

@pankajnarola1995 The issue is about Promise is not working on Safari, not GM_xmlhttpRequest, maybe you should open a new issue.

BTW, the HTTP request returns 401 Unauthorized status, meaning that you're not login to the server or the server got an invalid session and reject your request, maybe you should check is there something wrong with your script or website.

Hii, @ccloli thank you so much for reply. Yah I have noticed that and I have checked the login 10 times... and still, it's the same result..
The same happens into chrome and firefox browser when I did the log out, it threw the above error, but if I do the same in safari it's not working.. 😢

I'm not sure, maybe you should open a new issue and give a minimal script or steps that can reproduce your bug.
