Search API Media Fields

Here's a search processor.

Should we think of a generic solution, we have other modules like group_term and others.

@LOBsTerr, yes!!! See 📌 Search API Group Relationships across entity types Active .

When I apply this I get:
Doctrine\Common\Annotations\AnnotationException while computing Views data for index Social Groups: [Syntax Error] Expected PlainValue, got ''' at position 31 in class Drupal\groupmedia\Plugin\search_api\processor\GroupRelationshipMedia. in Doctrine\Common\Annotations\AnnotationException::syntaxError() (line 28 of drupal-10.3.x/vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/AnnotationException.php)
