Bean validation is not working in case of bulk create

[Desire456]

Given the following request:

POST {{baseUrl}}
         /entities
         /jmixp_Order
Authorization: Bearer {{auth_token}}

[
    {
        "name": null
    },
    {
        "name": null
    }
]

Note:
Order's name property has @NotNull constraint.

AR:

[
    {
        "_entityName": "jmixp_Order",
        "id": "05371460-eba8-b4b4-8aa6-7f9c52c95cf8"
    },
    {
        "_entityName": "jmixp_Order",
        "id": "5856d6e0-f538-2534-b9bc-a92f4003e4ad"
    }
]

ER:

{
    "message": "may not be null",
    "messageTemplate": "{javax.validation.constraints.NotNull.message}",
    "path": "name",
    "invalidValue": null
 }
