未找到主页子 tab: %w

Error message

未找到主页子 tab: %w

What it means

selectTab fails while querying the profile page's sub-tab elements via the CSS selector `.reds-tab-item.sub-tab-list` (xiaohongshu/user_profile.go:178). This error means the rod call to enumerate sub-tab elements itself errored (element lookup/eval failure), not that matching tabs are absent. GetMyProfileViaSidebar propagates it unchanged.

Solutions

1. Check the wrapped rod error — if it indicates no element, the page likely never rendered the tab bar; verify login state.
2. Re-navigate and retry after MustWaitStable.
3. If XHS renamed the sub-tab classes, update the `.reds-tab-item.sub-tab-list` selector.

resp, err := action.GetMyProfileViaSidebar(ctx, tab)
if err != nil && strings.Contains(err.Error(), "未找到主页子 tab") {
    // page never rendered the tab bar — re-navigate or check login
    return reLoginAndRetry(ctx)
}

When it happens

Trigger: Calling GetMyProfileViaSidebar with a non-default tab (e.g. TabCollect/TabLike) when page.Elements(`.reds-tab-item.sub-tab-list`) returns a rod error — page navigated away, JS context destroyed, or page closed.

Common situations: Profile page redirected to a login wall so the sub-tab bar never rendered; page crashed mid-navigation; browser disconnected.
