Anyone faces the same issue?

Answer 1

After testing on my pc just now, i take pleasure to report my findings as below :-

1. If we run the React Code in SoloLearn website version with Chrome, the output window is blank.

2. If we run the same React Code in a local html file with Chrome, it works.

Note that the //</script><... babel... > trick is removed in test 2 above.

To conclude, the codes are fine, the browsers are fine. It is SoloLearn protecting themselves from some suspicious acts such as //</script>

Answer 3

I sent feedback and links to my codes from my post about the same problem(look above👆). Hope they will explain the purpose and will give further instructions

I got an answer from support. They fixed a problem, guys. All works. Check out your masterpieces😎

Relax and keep coding🎫

As I said that it relates with crash of solo server🤔

Answer 6

Ohhh, it's so huge problem...

I noticed so many codes today with this annoying "postMessage" error. Not only with frameworks btw😭

Answer 7

My guesses were confirmed. Solo reinsured and thus removed the opportunity to work with the react(and other interesting libraries) on desktop? It's very inconvenient write the code in smartphone😕

I noticed that error occurs sometimes, but if I execute the code second or third time all become ok🤔 Will make the one more feedback about it.

Answer 9

That's why vanilla.js is the best, mature and stable framework😎

Rather than all these reacts, vues, angulars, etc...😁

Answer 10

Look in console too, Gordon
CrossOrigin I think.
And the most interesting thing they can return previous behavior to us🙂

Answer 11

Did anybody check other languages in playground? Are there some problems with python for example, or kotlin?
Maybe we must switch to other languages?🤔😂😂

Answer 12

The same shit🤔

Answer 13

I think solo developers must recover initial state soon. If they will get enough feedback from us

Answer 14

Calviղ Check the console output. Maybe you will understand the purpose of this.

Check my vue codes. They are working on my desktop

Answer 15

Maybe they continue recover server and changing some stuff. It's my assumptions only🤔 And our masterpieces stop working😂

Answer 16

The most funny thing that vue projects are working.
Another tick in favor of the Vue.js framework😁

Answer 17

Gordon Thank you so much for putting efforts ro test it on pc with code playground and local html/js files.

So we can conclude we cannot add babel codes on js pane.

I think we might still can run code playground react from pc browsers, we just need to put babel codes on html pane with script tag. Back to the initial method, before we discovered //script 😬

I would test it tomorrow. Gordon, thanks again for reminding me the trick //script might cause the issues. Good works always. 👍😁

Answer 18

Hopefully Sololearn trigger the cross domain setting soon. I switch to phone coding my react now.

Look like Sololearn has migration to Azure after the outrage.

4rontender Thanks for taking action to send feeback. I believe we would get positive feedback from Sololearn soon. 😊
