Code

public function getRelationUri($entity_type, $bundle, $field_name, $context = []) {

  // Per the interface documentation of this method, the returned URI may
  // optionally also serve as the URL of a documentation page about this
  // field. However, Drupal does not currently implement such a documentation
  // page. Therefore, we return a URI assembled relative to the site's base
  // URL, which is sufficient to uniquely identify the site's entity type +
  // bundle + field for use in hypermedia formats, but we do not take into
  // account unclean URLs, language prefixing, or anything else that would be
  // required for Drupal to be able to respond with content at this URL. If a
  // module is installed that adds such content, but requires this URL to be
  // different (e.g., include a language prefix), then the module must also
  // override the RelationLinkManager class/service to return the desired URL.
