(Is this a bug in EmbedSupport or VE or Beta Cluster?)

I Ithink it is a bug in MediaWiki-extensions-MwEmbedSupport causing problems with VisualEditor, but only in the Beta-Cluster-Infrastructure, but don't quote me on that.

Provisionally declaring this a problem with master, not the Beta Cluster.

OK, I think this may have been 'just' T107979: [Regression pre-wmf18] VisualEditor doesn't load, throwing "Uncaught TypeError: Cannot read property 'requestPageData' of undefined"; will mark as closed but if anyone can reproduce please re-open.

VE ~~now works~~ worked for a while, while logged out on the beta cluseter, however the big spinning "loading" thing is still on beta, and won't disappear. So something still...wrong.

Still can't use VE while logged in on the beta-cluster either.

I can't repro this; the blue bar stops at the end but I see no JS errors, just an alert() about HTTP 0?

So it doesn't look to me like MwEmbedSupport or TimedMediaHandler is involved here, as I can't reproduce the JS error but I can reproduce the blue bar halting. I'm pretty sure this has to do with the failure to reach the restbase server instead.

@Josve05a, do you see that error on regular page views as well? Do you still see it with a fresh account? In other browsers? (I do not on any count.) Do you still see the VE failure? (I do, always.)

The .js error I see constanly (presents itself with the spinning-thing). On all beta-cluster pages, both while logged in and not logged in. I only have access to this browser (on a Chromebook).
Mozilla/5.0 (X11; CrOS x86_64 7077.95.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.90 Safari/537.36
The VE-error I didn't see while logged out, thne when I logged in once it has "stuck" with me now.

Josve05a mentioned this in T108220: RESTbase is 500ing in Beta Cluster (after a long timeout).Aug 6 2015, 7:26 PM

This now seems to be working; I can't reproduce errors on pages with videos when logged out or with no cache…

Ok I can confirm VE's working for me on beta labs as well now; it definitely sounds like the VE error was unrelated to the JS error in MwEmbed/TMH. Shall we remove the blocker tags from this and leave the bug open for the JS error?

Given the errors were apparently coming from Multimedia code, I worried there was something broken there, like a RL module not being loaded in the right order or whatever.

But it now just looks like those were transient issues arising from the RB and VE issues. So I've closed it as 'Resolved', and on my head be it when wmf18 rolls out and all video/audio breaks. :-)

So, where does this leave the JS error in MwEmbed/TMH? Should I wat until the next wmf-release, or file/reopen this task to get that fixed?

Does that JS error still occur? Where, and doing what?

On http://en.wikipedia.beta.wmflabs.org/wiki/User:Josve05a-beta/sandbox?veaction=edit (and for all other pages on the beta-cluster) It has a "spinning" wheel which keeps loading, and the js error pops up in console.

Since I'm still experiencing the JS error on beta, and the VE bug was opened as a different task, I'm reopening this task to make sure we have a task for the JS-thing.

Experienicng this on svwp now, as well as
