Drupal 8 Rest API: Interfaz de Programación de Aplicaciones (API) de Drupal 8.

Mis API personalizadas están funcionando bien, he desplegado el código en el servidor de staging pero estoy obteniendo el siguiente error.

Drupal\Component\Plugin\Exception\PluginNotFoundException: El plugin “” no existe. Los ID de plugin válidos para Drupal\rest\Plugin\Type\ResourcePluginManager son: dblog, file:upload, entity:block, entity:blockcontenttype, entity:blockcontent, entity:comment, entity:commenttype, entity:configpagestype, entity:configpages, entity:contactform, entity:contactmessage, entity:editor, entity:fieldconfig, entity:fieldstorageconfig, entity:file, entity:filterformat, entity:flagging, entity:flag, entity:googleapi.serviceclient, entity:googleapiclient, entity:imagestyle, entity:menulinkcontent, entity:node, entity:nodetype, entity:pagevariant, entity:page, entity:pathalias, entity:rdfmapping, entity:restresourceconfig, entity:searchapitask, entity:searchapiserver, entity:searchapiindex, entity:searchapiautocomplete, entity:shortcutset, entity:shortcut, entity:socialauth, entity:menu, entity:action, entity:taxonomyterm, entity:taxonomyvocabulary, entity:tour, entity:ultimatecronjob, entity:user, entity:userrole, entity:webformoptions, entity:webform, entity:webformsubmission, entity:webformaccessgroup, entity:webformaccesstype, entity:webformimageselect, entity:webformoptionscustom, entity:view, entity:paragraph, entity:paragraphstype, entity:basefieldoverride, entity:entityviewdisplay, entity:entityviewmode, entity:entityformmode, entity:entityformdisplay, entity:dateformat, userregistration in Drupal\Core\Plugin\DefaultPluginManager->doGetDefinition() (line 53 of /home1/tourcode/publichtml/’/web/core/lib/Drupal/Component/Plugin/Discovery/DiscoveryTrait.php)

Gracias por adelantado.
