Trying to add a field to a view based on meilisearch index does nothing and a PHP error is returned/logged on Drupal 11 instance.
The logs show the following error.
TypeError: Drupal\Component\Utility\Html::escape(): Argument #1 ($text) must be of type string, null given, called in /var/www/html/web/core/lib/Drupal/Component/Render/FormattableMarkup.php on line 238 in Drupal\Component\Utility\Html::escape() (line 431 of /var/www/html/web/core/lib/Drupal/Component/Utility/Html.php).
On investigating the issue, the problem lies in how the module handles special search api fields. In 🐛 Error when indexing special fields (search_api_*) Fixed we clone special fields as backend defined fields, however this is incorrect as special fields are not meant to be visible and/or added through UI.
Since the special fields do not hold any labels the cloned backend defined fields also contain no label and the error is thrown.
A quick fix would be to use empty string where NULL labels are returned however the underlying issue should be fixed and special fields should be handled properly.

I've checked this branch locally with clean install of D11 and tested this by creating a new view and then applying sorting on the indexed attributes. I've also reviewed code in the MR and everything seems to be ok. Marking this as RTBC.
