Thanks for your report. I'm looking into log for more details.

Keep calm and stay waiting :)

Is this still happening?

OK. Last one happened on 20160627, can you try again?

hallo?

Basically this means we got HTTP 400 error (without body it seems) from restbase or parsoid. This should have corresponding errors in the parsoid log if it is about the draft content rather than other kind of outage.

Hmm, I clearly see the errors in EventLogging, for example:

trace: {"servedby":"mw1197","error":{"code":"docserver","info":"docserver-http: HTTP 400","*":"See https://id.wikipedia.org/w/api.php for API usage"}}
timestamp: 20160720134452

But I cannot find that in logstash. @Nikerabbit, can you find it?

OK, with @Nikerabbit's help I found that the actual error is "Cannot serialize transclusion without data-mw.parts or data-parsoid.src.". We'll investigate it further.

Keep waiting :)

keep waiting :D

it's still heppening :/

Owh :o, it's too hard?

@Alfan.nusantara Sorry for delay. I just checked in the log and this error last happened on 21st August 2016. Can you provide some more details?

1. Is it still happening (Try to publish article, check if reloading article throws an error).

2. Is there any Javascript console of the browser. Press Control + Shift + J to open it and observe any error(s). (See: https://developer.mozilla.org/en/docs/Tools/Browser_Console if you're not familiar with it).

3. Is there anything that can be useful to debug.

detail like what? like screenhot of Javascript in my browser?

Yes please, when you are trying to publish.

For easier viewing

@Alfan.nusantara, can you please try the same in another browser, for example Chrome?

How to open JS in chrome, if i press Control + Shift + J, there is a console and then i see a blank page?

(First, a general comment: @Alfan.nusantara, you can easily upload images to Phabricator by simply dragging the file from your desktop to the comment.)

From these screenshots I can see that it's not a client-side problem, but a server-side error, but I'm still not able to understand what it is. I'll need @santhosh's help.

thank's for your information about simple upload :)

Possibly related to T154116. Being tracked via the new bug now.
