I have a react app. There is a checkbox which disables the datepicker. But I can't select any date when I'm using checkbox to disable it. If I remove checkbox and its function there is no error. Currently, I'm getting:

date.clone is not a function

error.

const dateFormat = "YYYY-MM-DD";

const today = moment();



const [date, setDate] = useState(today);

const [disabled, setdisabled] = useState(false);



  



const onCheckboxHandle = (e) => {

    if (e.target.checked) {

      setwarntill(moment("2090-10-10"));

      setdisabled(true);

    } else {

      setwarntill(today);

      setdisabled(false);

    }

  };

<Checkbox onChange={onCheckboxHandle}>Süresiz</Checkbox>

        <Form.Item name={["user", "timetill"]} label="Uyarı Bitiş Tarihi">

          <ConfigProvider locale={locale}>

            <DatePicker

              defaultValue={moment()}

              format={dateFormat}

              onChange={(date,dateString) => setwarntill(dateString)}

              value={warntill}

              disabled={disabled}

            />

          </ConfigProvider>

        </Form.Item>
