String 对字符串symfony 3.4调用成员函数format（）

发送电子邮件后，我试图在数据库中注册一个新约会，但它显示了一个错误：调用字符串上的成员函数format（）， 在vendor\doctor\dbal\lib\doctor\dbal\Types\DateTimeType.php中 ,

因为在预订实体中，有我需要注册的日期和时间，它们是日期时间类型。 以下是预订实体：

谢谢

发生此错误是因为您试图在预订实体上将日期和时间设置为字符串

  $booking->setDateRdv('date');
  $booking->setHeureRdv('time');

尝试将其更改为：

  $booking->setDateRdv(new \DateTime($date));
  $booking->setHeureRdv(new \DateTime($time));

  $booking->setDateRdv(new \DateTime($date));
  $booking->setHeureRdv(new \DateTime($time));
