**Issue Evaluation**
Category: `bug` | Status: **Confirmed**
Verified against `master` branch
(`frontend-new/src/pages/Message/message.jsx`). Lines 105, 114-115 call
`.valueOf()` on `timepickerBegin` and `timepickerEnd` without null checks:
```jsx
if (timepickerEnd.valueOf() < timepickerBegin.valueOf()) { // line 105
...
timepickerBegin.valueOf(), // line 114
timepickerEnd.valueOf(), // line 115
```
When either DatePicker is cleared, the state becomes `null`, and
`null.valueOf()` throws `TypeError`. The DatePicker component allows clearing
(no `disabled` or `allowClear={false}` constraint).
**Severity:** medium — the query feature becomes unusable after clearing a
date field, with no user-friendly error.
**Impact:** Message query page.
Suggested fix: add null guards before `.valueOf()` calls; show a localized
prompt when dates are missing.
