this seems to be parsoid from git 45a32f444a7eed48e691b31931091a02185e06b6

We should be able to reproduce this on a local wiki with the contents of that template.

• Template source is: https://www.zabbix.org/mw/index.php5?title=Template:ZBX&action=edit ...
• Test snippet: {{ZBX|1}}

We know of some regressions from that commit. It is is not yet deployed onto production, but yes, master has failures. https://gerrit.wikimedia.org/r/#/c/123908/ may fix it (not yet merged).

The problem here is that interwiki link is redirecting from http to https. ex.

parsoidConfig.setInterwiki('zap', 'http://www.zabbix.org/mw/api.php');

should be

parsoidConfig.setInterwiki('zap', 'https://www.zabbix.org/mw/api.php');

did you recently switch to https only?

Template expansion is trying to query the api but getting a 301 redirect in response ... which produces the error instead of following it.

if the question about https was for me, there is a redirect for http -> https, but visual editor was installed recently and this problem was there from the very beginning.

given that i'm accessing the page over https, shouldn't it work automatically ?

the only non-https connection i can see is the wgVisualEditorParsoidURL, which goes to localhost http - but i'd prefer it to stay that way (and i'm not sure whether that would help anyway :) )

What do you have set in your parsoid configuration?

that was set to http://localhost/mw/api.php

if i set it to https, in the browser i get :

Error loading data from server: parsoidserver-http-request-error: MWHttpRequest error. Would you like to retry?

and in node.js error :

TypeError: Cannot call method 'substr' of undefined

(i have set it back to http for now)

right, you're getting a 404 for https://localhost

try setting that to https://www.zabbix.org/mw/api.php

or, alternatively, when you visit http://localhost/mw/api.php, does that try to redirect you? change your http server configurations to allow non-https connections on localhost

oh, neat - disabling https redirect for localhost seems to have helped, huge thanks.

maybe a bit more friendly error messages can be returned in case of 301/404 errors ?

yeah, I'm working on that now based on these reports. we've recently changed the way we log data and there're still some bugs.

glad to hear it's working for you.
