断言日期验证错误[symfony]

Question

When I'm trying validate $date with assert, like this : @Assert\Date()

 /**
 * @ORM\Column(type="date")
 * @DatagridColumn(sortable=TRUE)
 * @Assert\Date()
 * @Assert\NotBlank()
 */
private $date;

But I have an error :

Error: Call to a member function format() on string

500 Internal Server Error - FatalErrorException

Does anyone know, why it's happening ?

From documentation: TYPE could be string.

I also checked the format using dump() and it's correct > YYYY-MM-DD

Without validation it works correct.

Thank you for any information

You have this error because the property $date is a string, but should be an object DateTime.
