#The id field definition does not exist and it is used as id entity key
我自定义了一个日志实体，但是在安装module的时候报错：The id field definition does not exist and it is used as id entity key

#代码：

<?php

namespace Drupal\ixtend_log\Entity;

use Drupal\Core\Entity\ContentEntityBase;
use Drupal\Core\Entity\ContentEntityInterface;
use Drupal\Core\Entity\EntityTypeInterface;
use Drupal\Core\Field\BaseFieldDefinition;
