Put Task API has a problem

Hello All

When we have updated the task with API, API deletes the due date and name.

before update task

[
    {
        "id": "4253c190-58db-11ec-9f86-acde48001122",
        "name": "asdasd",
        "created": "2021-12-09T10:32:07.551Z",
        "due": "2021-12-14T10:32:07.475Z",
        "delegationState": "PENDING",
        "executionId": "42532545-58db-11ec-9f86-acde48001122",
        "processDefinitionId": "asd:43:efb7d692-58da-11ec-9f86-acde48001122",
        "priority": 0,

        "taskDefinitionKey": "asd_Form",
        "suspended": false
    }
]

after update task

    {
        "id": "4253c190-58db-11ec-9f86-acde48001122",
        "created": "2021-12-09T10:32:07.551Z",
        "delegationState": "PENDING",
        "executionId": "42532545-58db-11ec-9f86-acde48001122",
        "processDefinitionId": "asd:43:efb7d692-58da-11ec-9f86-acde48001122",
        "priority": 1,
        "processInstanceId": "3a473543-58db-11ec-9f86-acde48001122",
