title: Facebook debugger not reading OG tags
body: <p>I am creating a page for a largely static website. This page is generating customized URLs for Facebook Share buttons. I am trying to share individual images or MP4 videos on the page, not the page itself. The _GET info in the URL is determined by the link clicked and PHP modifies the OG tags with the relevant info. I am trying to set it up so the share preview will show a thumbnail along with the title and description.</p>
  <p>On the page itself the image share links work fine but the video share links produce a 403 error even though the links are correct and I can open the videos manually with no problem. When I try to view the &quot;<em>See exactly what our scraper sees for your URL</em>&quot; link on the Debugger page it just shows a blank page.</p>
  <p>Facebook debugger receives URL's like</p>
  <p><a href="https://checkthenshare.ca/share-dev.php?image=covid-Check-First-th.png&amp;video=MS_Social_CFSA.mp4" rel="nofollow noreferrer">https://checkthenshare.ca/share-dev.php?image=covid-Check-First-th.png&amp;video=MS_Social_CFSA.mp4</a></p>
  <p>It return's errors like,</p>
  <p><em>Inferred Property : The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.
  Missing Properties : The following required properties are missing: og:url, og:type, og:title, og:image, og:description, fb:app_id</em></p>
  <p>The OG code that is being produced looks okay to me but I don't have a lot of experience with it.</p>
  <pre><code>    &lt;meta property=&quot;og:url&quot; content=&quot;https://checkthenshare.ca/img/stories/MS_Social_CFSA.mp4&quot; /&gt;
      &lt;meta property=&quot;og:title&quot; content=&quot;Check first. Then Share.&quot; /&gt;        
      &lt;meta property=&quot;og:description&quot; content=&quot;Passing on false content can be like passing on COVID-19 itself. And that can be deadly. Before you share, pause, check the source, and make sure it&amp;apos;s legit. Check First. Share After. https://checkthenshare.ca&quot; /&gt;
      &lt;meta property=&quot;og:site_name&quot; content=&quot;Check first. Then Share.&quot; /&gt;
      &lt;meta property=&quot;og:type&quot; content=&quot;video.other&quot; /&gt;  
      &lt;meta property=&quot;og:image:url&quot; content=&quot;https://checkthenshare.ca/img/covid-Check-First-th.png&quot; /&gt; 
      &lt;meta property=&quot;og:image&quot; content=&quot;https://checkthenshare.ca/img/covid-Check-First-th.png&quot; /&gt;
      &lt;meta property=&quot;og:image:width&quot; content=&quot;540&quot; /&gt;
      &lt;meta property=&quot;og:image:height&quot; content=&quot;960&quot; /&gt;         
      &lt;meta property=&quot;og:locale&quot; content=&quot;en_CA&quot; /&gt;
      &lt;meta property=&quot;og:video:type&quot; content=&quot;video/mp4&quot; /&gt;
      &lt;meta property=&quot;og:video:url&quot; content=&quot;https://checkthenshare.ca/img/stories/MS_Social_CFSA.mp4&quot; /&gt;
      &lt;meta property=&quot;og:video&quot; content=&quot;https://checkthenshare.ca/img/stories/MS_Social_CFSA.mp4&quot; /&gt;
      &lt;meta property=&quot;og:video:width&quot; content=&quot;1080&quot; /&gt;
      &lt;meta property=&quot;og:video:height&quot; content=&quot;1920&quot; /&gt;

  <p>I am hoping some hawk-eyed person can spot some error in my tags. I am going crossed eyed staring at them.</p>
  <p>Thanks!</p>
