What causes "输入日期时间失败" in xpzouying/xiaohongshu-mcp?

Re-acquire the element and retry the full SelectAllText + Type sequence once.

输入日期时间失败

Error message

输入日期时间失败

What it means

Thrown by setDateTime when humanize.Type fails to type the formatted datetime string into the input. Humanized typing simulates keystrokes; it fails if the element detaches mid-typing, focus is stolen, ctx is cancelled, or the page closes.

Solutions

Re-acquire the element and retry the full SelectAllText + Type sequence once.
Ensure ctx has an adequate deadline for the typing duration.
Dismiss any popup calendar overlaying the input before typing.
Verify the input still accepts keyboard events on the live XHS page; update the typing strategy if the component changed.

Example fix

// before
if err := humanize.Type(ctx, elem, dateTimeStr); err != nil {
	return errors.Wrap(err, "输入日期时间失败")
}
// after
if err := humanize.Type(ctx, elem, dateTimeStr); err != nil {
	elem, err = page.Element(".date-picker-container input")
	if err != nil {
		return errors.Wrap(err, "查找日期时间输入框失败")
	}
	_ = elem.SelectAllText()
	if err := humanize.Type(ctx, elem, dateTimeStr); err != nil {
		return errors.Wrap(err, "输入日期时间失败")
	}
}

Defensive patterns

Strategy: try-catch

Validate before calling

ctx, cancel := context.WithTimeout(context.Background(), 30*time.Second)
defer cancel()

Try / catch

if err := setSchedulePublish(ctx, page, t); err != nil {
	if errors.Is(err, context.DeadlineExceeded) || strings.Contains(err.Error(), "输入日期时间失败") {
		slog.Warn("datetime typing failed, retrying once")
		return setSchedulePublish(ctx, page, t)
	}
	return err
}

Prevention

Give the typing context enough deadline for the full keystroke simulation.
Close calendar popups that may steal focus before typing.
Verify the field value after typing (elem.Text() or Eval on .value) to confirm success.
Keep the picker panel stable — avoid clicking elsewhere between select and type.

When it happens

Trigger: A popup calendar steals focus mid-typing; the picker re-renders as characters are typed; ctx deadline expired; the input rejects synthetic key events after an XHS front-end change.

Common situations: Slow environments where typing outlasts a re-render; automation runs with a short-lived context; XHS input validation closing the picker on invalid intermediate values.
