• I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

Steps to reproduce

export const DatePickerUpdateTest = () => {
  const initTime = '2077-07-07 07:07:07';

  const [form] = Form.useForm();

  useEffect(() => {
    form.setFieldsValue({ time: moment(initTime) });
  }, [form]);

  return (
    <div style={{ padding: 20 }}>
      <Form form={form} name="infoForm" layout="vertical">
        <Form.Item name="time" rules={[]} label="TIME">
          <DatePicker showTime />
        </Form.Item>
      </Form>

      <Button type="primary" onClick={() => form.setFields([{ name: 'time', value: moment() }])}>
        Success Update
      </Button>

      <Button
        danger
        style={{ marginLeft: 10 }}
        // TODO console get some error
        // Uncaught TypeError: val.isValid is not a function
        // The above error occurred in the <PickerWrapper> component:
        onClick={() => form.setFieldsValue({ time: moment() })}
      >
        Fail Update
      </Button>
    </div>
  );
};

What is expected?

setFieldsValue can correctly verify moment() or Date.

What is actually happening?

setFieldsValue check for moment() or Date error. but setFields succeeds. why?

##我也遇到了同样的问题，请问解决了吗？
refForm.current?.setFieldsValue({ ...slcData.current, birthday: '2020-01-22' })

Error:

moment.js:105 Uncaught TypeError: date.clone is not a function at Object.format (moment.js:105)

Same here can not get any initialValues to load correctly and it breaks the whole page I have tried moment date and string representations. This particular example is in a form.list but it also happens outside of it.

If you cast your Date object into moment object first, this error disappears.

今天我也出现了这个报错，然后发现，在set之前，用dayjs库给入参（元数据）的日期时间字符串包裹一下生成dayjs的日期对象就没有那个报错了，just like this:

value: dayjs(eventInfo.date)
