I can't make my open graph tags accessible to Facebook. When I try to share a page, the site links properly, but the og attributes don't show up, and the title just displays as "422". I'm not sure what this means.
When I run the facebook debugger https://developers.facebook.com/tools/debug/og/object/ I get the following error, which isn't very helpful:
Error parsing input URL, no data was cached, or no data was scraped.
Using the echo feature in the debug tools, all I get is:
Document returned no data
The meta tags appear to be set up properly in my document:
<!DOCTYPE html>
<html>
<head prefix="og: http://ogp.me/ns# fb: http://ogp.me/ns/fb#">
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="robots" content="noarchive,noodp,noydir" />
<meta name="referrer" content="always" />
<meta property="fb:app_id" content="375576830972731" />
<meta property="og:site_name" content="Site Name" />
<meta property="og:title" content="Title of content" />
<meta property="og:url" content="https://website.domain.com/123456" />
<meta property="og:image" content="http://s3-us-west-1.amazonaws.com/domain/media/images/001/original/001" />
<meta property="og:description" content="Description of content" />
<meta property="og:type" content="article" />
</head>
I made sure to allow for the Facebook crawlers in robots.txt:
User-agent: Facebot
Allow: /
User-agent: facebookexternalhit/1.1
Allow: /
What I am I missing?
The problem here was my protect_from_forgerymethod in application.rb. I added an exception and the Facebot can now see the page.
class StoriesController < ApplicationController
protect_from_forgery except: :show
