TypeError: Cannot access offset of type array on array

Problem/Motivation

Installed the module and when trying to export I get:

TypeError: Cannot access offset of type array on array en Drupal\Core\Entity\EntityStorageBase->load() (linea 264 de /var/www/......../web/core/lib/Drupal/Core/Entity/EntityStorageBase.php).
