Timezone breaks submission: "cannot read join of null.

[ghost]

I cann't press the button "Submit and go to my next challenge (ctrl + enter)". But if I clicked I only see the infinite loading. How to solve this problem?

[AkiraLaine]

What browser/OS are you using?

[ghost]

Chrome

[AkiraLaine]

What OS? Also, are you using a VPN?

[ghost]

Windows 7 Ultimate.No I'm not using

[AkiraLaine]

Ok, I'm not sure how that happens...weird.

i have same issue ( ( windows 7 , last chrome)

[AkiraLaine]

I can confirm. I am having the same issue on some challenges.

EDIT: Not happening any more. What about you guys?

[zelda322]

@AkiraLaine still not working

[QuincyLarson]

I can't reproduce on latest Chrome with OSX. @AkiraLaine are you on Windows? Can anyone with Windows confirm this is still a problem?
@Park23 could you open up your browser console and take a screen shot of any errors you see? Also, which challenge are you experiencing this on?

[AkiraLaine]

@QuincyLarson No I cannot reproduce it.

Also if you have this issue, please, comment here a screenshot of your browser's Network tab.

[bugron]

@Park23 is that all? Isn't there a POST request for /completed-challenge/?

[zelda322]

@bugron it's all

[bugron]

@Park23 are you behind any VPN, anonymization soft, proxy, firewall? Are you browsing from your school/internet cafe/any other public place? Because they may have a firewall which is blocking your connection.

[zelda322]

@bugron Just router in home, 2 hour later all was fine

[bugron]

@Park23 and the last question. Where are you located if you don't mind me asking? I recommend you to try this https://github.com/FreeCodeCamp/FreeCodeCamp/wiki/Using-browsec-for-securing-your-connection-to-fcc.

@bugron Middle Asia)

[evaristoc]

tried the registration challenges: can't replicate, @bugron
Windows 10; Amsterdam; Google Chrome

I did notice a short delay though

[bugron]

@evaristoc I'm not able to repro too. Not sure what is the issue. I thought this is something related to their connection (kinda a VPN, firewall or proxy is blocking things) but I'm in doubt now after @Park23 said that there isn't a POST request for /completed-challenge/. When you click that button script makes a /completed-challenge/ POST request to send the completion data to the server. There is no such a request which means that something went wrong before a request has been made.

[evaristoc]

That suggests that it could be broken at client...

@bugron we rencently introduced a change in the ga functionality (I wonder if that change is breaking the completion script...)

[bugron]

This is what I'm talking about (after clicking the button):

The emphasized redirection takes place only when that POST request is successful.
@evaristoc not sure if that is related to this issue.

[bugron]

I see that jQuery isn't loaded for @Park23. We send the POST request using jQuery's $.post so it will fail. @Park23 if you still have this issue try to find out why jQuery isn't loading.

[evaristoc]

@bugron yes, I couldn't find any reason why the change to the ga functionality
could have broken the post request...

Hi guys! Same here with "submit and go to my next challenge" screen hanging. Everything was fine until now. Chrome/Windows 7. Can this be a server lagging?

[sukrosono]

So this just happen in windows user?

[cannelflow]

[iritu]

It stucks in this position, not working, for 2 days, tried in Edge and Chrome, nothing helps, it worked perfectly a few days ago so please don't blame my WIN10 or my computer it something to do with your system, please do check it.

[raisedadead]

@iritu Can you use Firefox meanwhile? seems to have worked for others in the comments above.

[iritu]

Yes, this is what I did, try to fix the problem with Chrome, please....Tnks.

[sebastian-kreft]

Firefox works for me. Waiting for Chrome fix, please :)

[ImSerenityADev]

There are 64 and 32 bit Chrome versions. Saw Windows 7 mentioned. Any of the posts mention/ include this info? (i.e., which version of Win7 ( (32/64) not sure that it would be relevant though)

[noncasus]

No issues here but I'm usually signed out so it could be that one must sign in to get past this issue.

Win10/Chrome 48.0.2564.97

[sukrosono]

@sebbe88 can you try with closing the tab and try again with chrome?
or try with signed out and sign in again?

[YangLeda]

Same problem. I have 2 computuers at my home, windows7 + chrome / windows10 + edge. Both have the same problem. Home WiFi, no VPN. I'm in China. I haven't try firefox since I don't like it. Thanks a lot if anybody gonna fix this.

[aleksej3455]

same error appear, win 7 + chrome
made 112 challanges in one day, took 4 days break and - Uncaught TypeError: Cannot read property 'join' of null is what i have now

p,s: also everything works fine in chrome if you not loggedin in private mode

[BerkeleyTrue]

Thanks everyone for reporting. This is a bug in moment-timezones code. I'll put together a patch shortly while we wait for an official fix from them.

In the meantime please use FireFox.

[SaintPeter]

Can everyone report if they have their OS language set to a non-English language and/or a non-western alphabet/character set (IE: Cyrillic)?

If so, does changing your language to english help?

[BerkeleyTrue]

A patch is up on beta. Give it a try and report back.

[sukrosono]

@BerkeleyTrue will report if any user in gitter have this issue.

[BerkeleyTrue]

A patch has been released to production. This patch will be removed when new version of moment-timezone is release with permanent fix.
