Problem/Motivation
When previewing a view using the Views module, this error shows up:
Error: Call to undefined method Drupal\external_entities\ExternalEntityStorage::getTableMapping() in Drupal\views\Entity\Render\TranslationLanguageRenderer->getLangcodeTable() (line 55 of /var/www/html/core/modules/views/src/Entity/Render/TranslationLanguageRenderer.php).

Steps to reproduce
- Enable the External Entities Views Integration (Experimental) module (
xntt_views).
- Create and configure an external entity.
- Create a new View based on the created external entity.
- Add a field.
- Notice an error in the console:
An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /en/admin/structure/views/view/temporary_ee_view/preview/page_1 StatusText: 500 Service unavailable (with message) ResponseText: The website encountered an unexpected error. Try again later.Error: Call to undefined method Drupal\external_entities\ExternalEntityStorage::getTableMapping() in Drupal\views\Entity\Render\TranslationLanguageRenderer->getLangcodeTable() (line 55 of core/modules/views/src/Entity/Render/TranslationLanguageRenderer.php).
View configuration
Proposed resolution
It looks like the method isn't implemented in the root module. Maybe we need to add it?
Remaining tasks
