Answer 1

 $default_value = array_filter($default_value);

刚刚为我添加了代码及其工作。

Index: core/lib/Drupal/Core/Field/EntityReferenceFieldItemList.php

public function defaultValuesFormSubmit(array $element, array &$form, FormStateInterface $form_state) {
     $default_value = parent::defaultValuesFormSubmit($element, $form, $form_state);
//just add this line 
$default_value = array_filter($default_value);

     // Convert numeric IDs to UUIDs to ensure config deployability.
     $ids = array();

错误：在Drupal 8中调用null上的成员函数uuid（）
