Argument $entity is declared as string but uses in the code as object.

Problem/Motivation

Argument $entity is declared as '@param string $entity' in SchemaMetatagManagerInterface.php but uses in the code as object:

  // SchemaMetatagManager.php
  public static function getRenderedJsonld($entity = NULL, $entity_type = NULL) {
    // If nothing was passed in, assume the current entity.
    // @see schema_metatag_entity_load() to understand why this works.
    if (empty($entity)) {
      $entity_type = $entity->entity_type;  //line 102
      $entity = menu_get_object($entity_type);
    }
  ...

Proposed resolution

Propose to change declaration of argument $entity to '@param object $entity'.
