Facebook share gives wrong logo

Bug confirmed on Facebook.

There is indeed no og:image in the metadata, so the social platforms are left to figure it out for their own.

<meta property="og:site_name" content="Drupal.org" />
<meta property="og:type" content="article" />
<meta property="og:url" content="https://www.drupal.org/project/webmasters/issues/3177593" />
<meta property="og:title" content="Facebook share gives wrong logo" />
<meta property="og:description" content="Problem/Motivation Sharing any drupal.org link on Facebook (or maybe any social media) gives a different logo, which is of QED42&#039;s, a drupal.org top-contributor. Steps to reproduce Share any drupal.org link on Facebook. Proposed resolution That logo has alt attribute but it seems Drupal log doesn&#039;t. Remaining tasks None User interface changes None" />

Checked with the twitter card validator it just does not pick an image. https://cards-dev.twitter.com/validator I guess Facebook is trying to outsmart that.

The Facebook sharing validator is at:

https://developers.facebook.com/tools/debug/

but you need a Facebook account to use; perhaps even a Facebook developer account, which can be set up quickly.

https://developers.facebook.com/tools/debug/?q=https%3A%2F%2Fwww.drupal....
shows the QED logo.

shows a correct drupal logo

Hopefully helpful screenshot:

The section, issue, and probably others, content types need a default metatag configuration for this.

I've updated the metatag config for a few content types. https://git.drupalcode.org/project/drupalorg/commit/729b97e I think that'll fix it for sections and events ( I forgot to stick the issue # in the commit message). Issue fix is coming shortly.

These fixes have been deployed.

Closed (fixed) issues can only be re-opened by each project’s maintainer. It is almost always best to open followup issues rather than update closed issues.

This fix was only for issues. https://www.drupal.org/project/add_more_alternate is a module project. (Please also always include URLs whenever relevant, being able to click to the example is helpful.) I went ahead and put in configuration for most project types: https://git.drupalcode.org/project/drupalorg/commit/c000fb2
