I noticed some pages we crawled containing error message like this;
<div id="mw-content-text" lang="zh-CN" dir="ltr"
class="error">Failed to render property P373:
Wikibase\LanguageWithConversion::factory: given languages do not have the
same parent language</p>
But when I open the url in browser, there is no such message. And using
index.php can also get normal content without error messages.
Here are examples you can retry:
$ wget 'http://zh.wikipedia.org/zh-cn/Google'
$ wget 'http://zh.wikipedia.org/w/index.php?title=Google'
Looks like something is wrong on Wikipedia side, anything need to fix?
