Question

我正在尝试实现FOSMessageBundle，但每当我尝试访问任何消息或非空消息列表（发送/接收/删除）时，我都会收到此错误：

Fatal error: Call to a member function getId() on null

in vendor/friendsofsymfony/message-bundle/FOS/MessageBundle/Model/Message.php at line 160

public function getMetadataForParticipant(ParticipantInterface $participant)
{
    foreach ($this->metadata as $meta) {
        if ($meta->getParticipant()->getId() == $participant->getId()) {
            return $meta;
        }

    }

我不知道为什么它无法获取参与者信息。数据已正确保存在数据库中，我已根据文档按照安装说明进行操作。

这是我的用户实体：

我的config.yml：

fos_message:
    db_driver: orm
    thread_class: AppBundle\Entity\Thread
    message_class: AppBundle\Entity\Message

消息类：

namespace AppBundle\Entity;
