Playground on mac chrome stopped working

Hi All,
I am on macbook pro (macOs BigSur 11.6.3) using chrome browser. Playgrounds stopped working. Anyone else seeing this?

-k

Can you share the error?

The tab panel is all white. This is the error from developers tool console:

index.js:99 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading ‘length’)
at loadInSequence (index.js:99:27)
at index.js:115:9
at new Promise ()
at checkBabylonVersionAsync (index.js:114:12)
at index.js:119:1

Looks like your local storage might be corrupt. Can you log it out here from the dev console?

for (i = 0; i < localStorage.length; i++)   {
    console.log(localStorage.key(i) + "=[" + localStorage.getItem(localStorage.key(i)) + "]");
}

edit: actually just need localStorage.getItem("version")

I think you chose “local”. @RaananW can you fix this?

Now I have a white screen! :smile:

In the meantime @kri100s - you can run this:

localStorage.setItem("version", "4.2.0")

I am not sure what do you mean. Where should I run it? I get the white screen in the tab even I go to https://www.babylonjs-playground.com/ not running any code.

Ok, Its back. Playgrounds working again.

Confirm I am seeing the same. Chrome / Windows 10. Hitting playground results in white screen and the same error in console. Opening with incognito, it works.

> localStorage.getItem("version")
'4.2.1'

@RaananW might be a version redirection missing here ? in the new playground ?

In case it helps, I can see in the code being loaded that there is no “4.2.1” key in the Versions array.
