API page: https://api.drupal.org/api/drupal/developer!topics!forms_api_reference.h...
There is a link to Ajax Commands that can be used with the Ajax callback function in Form API, but this link is not working (anymore).
It is precisely at this point: https://api.drupal.org/api/drupal/developer!topics!forms_api_reference.h...
Description: Specifies the name of a callback function which will be called during an AJAX call. It can return HTML, a renderable array, or an array of AJAX Commands...
The link on AJAX Commands does not work. I guess the correct link will be:
https://api.drupal.org/api/drupal/includes!ajax.inc/group/ajax_commands/7.x
The same is true for the link at https://api.drupal.org/api/drupal/developer!topics!forms_api_reference.h... - the link on the anchor itself which should now point to:
https://api.drupal.org/api/drupal/includes!ajax.inc/group/ajax/7.x

It's likely this issue predates Contrib.social: some issue and comment data are missing.
This is for the Drupal 7 Form API reference. Since Drupal 7 is past end-of-life this is now a "won't fix".
