failed to navigate to profile page via sidebar

Error message

failed to navigate to profile page via sidebar: %w

What it means

GetMyProfileViaSidebar wraps any failure from navigate.ToProfilePage — the sidebar-driven navigation to the logged-in user's profile page (xiaohongshu/user_profile.go:156). This library drives a real browser via go-rod, so navigation can fail if the sidebar element is missing, not clickable, or the target page never loads. The wrapped inner error from Navigate.ToProfilePage carries the specific cause.

Solutions

Inspect the wrapped cause (%w) to see whether it is element-not-found vs timeout vs context cancelled.
Re-login / refresh cookies so the sidebar renders with the profile entry.
Retry with a fresh page and a live context; check network stability.
If XHS changed its DOM, update the sidebar selectors in the Navigate action.

Example fix

// before
resp, err := action.GetMyProfileViaSidebar(ctx, xiaohongshu.TabNotes)
// after
if err := ensureLoggedIn(ctx, browser); err != nil {
    return fmt.Errorf("login required before profile fetch: %w", err)
}
resp, err := action.GetMyProfileViaSidebar(ctx, xiaohongshu.TabNotes)

Defensive patterns

Strategy: retry

Validate before calling

if _, err := store.LoadCookies(); err != nil {
    return fmt.Errorf("login required before GetMyProfileViaSidebar: %w", err)
}

Try / catch

resp, err := action.GetMyProfileViaSidebar(ctx, tab)
if err != nil {
    var navErr *NavigationError // or inspect errors.Unwrap chain
    log.Printf("sidebar nav failed: %v", err) // wrapped cause is in err chain
    return fmt.Errorf("profile fetch failed: %w", err)
}

Prevention

Ensure a valid logged-in session (fresh cookies) before calling.
Pass a non-cancelled context with sufficient deadline.
Retry transient navigation failures with backoff.
Watch for XHS frontend updates that change sidebar markup.

When it happens

Trigger: Calling GetMyProfileViaSidebar(ctx, tab) when the sidebar '我' (profile) entry cannot be found or clicked: not logged in, sidebar DOM changed, page stuck loading, or browser context cancelled/timed out.

Common situations: Expired or missing login session so the sidebar renders differently; XHS frontend markup update renaming sidebar selectors; slow network exceeding the 60s page timeout; ctx cancelled by caller.
