I’m getting this error currently on my Discourse install (and here too) whenever I try to make a post that includes a link that fails to onebox, for whatever reason. I can’t really discern why some links are successfully “oneboxing” and some aren’t.
So for example, this link works:
(I love that it’s picking up on WordPress SEO head tags, by the way!)
And then this link, doesn’t (and I can’t include it on a separate line, unformated, otherwise I get the error):
My only hunch is that the second link failed because that specific page is so lengthy. So, there are two bugs here:
- The onebox failing
- The post not going through because of the failed onebox
