如何修复学说（Symfony 4）中发生的异常？

Question

我在phpmyadmin中添加了一个列到我的mysql数据库中。现在我想要更新我的实体。所以我在终端写了这个命令：

php bin/console doctrine:schema:update --force

但是我收到了错误消息

在AbstractMySQLDriver.php第98行：

执行'ALTER TABLE members RENAME INDEX uniq_c2502824f81e0671 TO UNIQ_45A1D21 F185E0617'时发生异常：

SQLSTATE [42000]：语法错误或访问冲突：1064 SQL语法中有错误;查看与您的MySQL服务器版本对应的手册，以便在第1行的“INDEX uniq_c2502824f81e0671 TO UNIQ_45A1D21FF85E0617”附近使用正确的语法

这是我的实体：

<?php

/**

        return null;
    }

    }

    }

    public function eraseCredentials()
    {
    }

    /** @see Serializable::serialize() */
    public function serialize()
    {
        return serialize(array(
            $this->id,
            $this->username,
            $this->password,
            // see section on salt below
            // $this->salt,
        ));
    }

    /** @see Serializable::unserialize() */
    public function unserialize($serialized)
    {
        list (
            $this->id,
            $this->username,
            $this->password,
            // see section on salt below
            // $this->salt
        ) = unserialize($serialized, ['allowed_classes' => false]);
    }
}
