尝试访问 null 类型值的数组偏移量（Emailvalidator）

Question

我有一个 CMS 库管理员。与数据库的所有连接都正常工作，它使新用户、新帖子、删除帖子、编辑帖子......但是当我尝试点击“我忘记密码”并点击通过邮件发送密码时，或者我尝试创建一个新的用户帐户（用户帐户已创建但没有激活，因为它不发送任何验证邮件），它显示此错误：

(1/1) ErrorException
Trying to access array offset on value of type null

in Parser.php line 147

如果我转到那一行，它会显示：

我也附上了完整的错误调试：

(1/1) ErrorException
Trying to access array offset on value of type null
