swagger传值为空，Field error in object ' ' on field ' '，: rejected value [null]

Question

问题遇到的现象和发生背景 之前也是这样写的，但是就没出现传值为空的问题

问题相关代码，请勿粘贴截图 表单类

@Data
@Schema(description = "查询任务分页列表表单")
public class SearchTaskByPageForm {

@Pattern(regexp = "^[\\e4e00-\\u9fa5]{2,20}$", message = "creatorName内容不正确")
private String creatorName;

@Pattern(regexp = "^员工请假$|^会议申请$", message = "type内容不正确")
private String type;

@Pattern(regexp = "^[0-9a-zA-Z\\-]{36}$", message = "instanceId内容不正确")
private String instanceId;

@NotBlank(message = "status不能为空")
@Pattern(regexp = "^待审批$|^已审批$|^已结束$", message = "status内容不正确")
private String status;


@NotNull(message = "page不能为空")
@Min(value = 1, message = "page不能小于1")
private Integer page;

@NotNull(message = "length不能为空")
@Range(min = 10, max = 100, message = "length必须在10~100之间")
private Integer length;

}

Controller类：

@PostMapping("/searchTaskByPage")
@Operation(summary = "查询分页任务列表")
@SaCheckPermission(value = {"WORKFLOW:APPROVAL", "FILE:ARCHIVE"}, mode = SaMode.OR)
public R searchTaskByPage(@Valid @RequestBody SearchTaskByPageForm form) {
    HashMap param = JSONUtil.parse(form).toBean(HashMap.class);
    int userId = StpUtil.getLoginIdAsInt();
    param.put("userId", userId);
    param.put("role", userService.searchUserRoles(userId));
    PageUtils pageUtils = approvalService.searchTaskByPage(param);
    return R.ok().put("page", pageUtils);
}

报错信息:

Field error in object 'searchTaskByPageForm' on field 'page': rejected value [null]; codes [NotNull.searchTaskByPageForm.page,NotNull.page,NotNull.java.lang.Integer,NotNull];

我的解答思路和尝试过的方法 我知道是传值为空，但我是不知道怎么改

我想要达到的结果 想要把值传入form类中，不为空

这个逗号去掉。
