I’ve never developed with Ruby before so I’m struggling to understand why OneBox is returning with a blank preview from our link, when iFramely and Slack render it fine. Here is a sample link we are trying to render, it has been whitelisted in our Discourse instance. https://link.jig.space/kEhFbFw…

A curl request responds with html which seems like it’s actually rendering the whole card. curl -X GET https://link.jig.space/gXszoFiWkX <html amp>  <link rel="alternate" href="ios-app://1111193492/jigspaceviewer/op…

I feel your pain in general though. When oneboxing fails could we have some additional logging to say exactly why it is turning its nose up?

Yeah it’s just that I can’t follow the code past here: lib/oneboxer.rb 102be5a9e max_width: 695, sanitize_config: Sanitize::Config::DISCOURSE_ONEBOX } options[:cookie] = fd.cookie if fd.cookie …

byebug is extremely useful. It’s already included in the project I believe, so just put the command ‘byebug’ on it’s own line of the code and the console will pop into the code at that point. Type any variable to find it’s value. Use commands ‘next’, ‘step’ and ‘up’ to get around. ‘continue’ to…

I didn’t realise onebox is it’s own gem. I’ve just discovered the onebox repo and it has some awesome points: https://github.com/discourse/onebox Reading the readme there: I should be able to make an engine myself to get around any og tag issues. I can’t see any onebox option for a debug flag or …

Yup it’s a ‘separate’ project. I’m in complete agreement about the logging. This should be verbose by default for all failures. We shouldn’t be having to break into the code to see what’s going on: it’s too common a Production problem. Facebook og debug is a nice extra, but onebox has made the…

Does it have actual text? Image only oneboxes aren’t supported.

Hi @codinghorror ! What do you mean by actual text? As an example here are some of the meta og tags returned from https://link.jig.space/gXszoFiWkX <meta property="og:title" content="Macintosh - Complete"> <meta property="og:description" content="Apple Macintosh Computer"> <meta property="og:image…

My guess is you don’t meet our minimum text content requirement for the onebox.
