查找旧版发布按钮失败

Error message

查找旧版发布按钮失败

What it means

findPublishButton wraps failures from page.Elements(".publish-page-publish-btn button.bg-red") — the legacy publish button selector — with this message. This fallback only runs when no new-style widget was found; the query failing means the old-version button could not even be searched.

Solutions

1. If it propagates (it normally is retried by the polling loop), retry the publish
2. Confirm the publish page actually loaded (check URL /publish/publish)
3. Check the browser tab is alive and not crashed
4. Update the library if Xiaohongshu removed the legacy button markup

// 确认发布页已加载
if !strings.Contains(pageMustInfo(page).URL, "/publish/publish") {
    return errors.New("尚未进入小红书发布页")
}

err := xhs.Publish(...)
if err != nil && strings.Contains(err.Error(), "查找旧版发布按钮失败") {
    err = xhs.Publish(...) // 轮询内部会自动重试；此处兜底
}

When it happens

Trigger: The CSS-selector query against the browser errors: page crashed or navigating, execution context destroyed, or the tab closed while probing the legacy selector.

Common situations: Publishing on a Xiaohongshu page version where neither button style is present; page reload mid-probe; browser instability.
