切换到 %s 失败: %w

Error message

切换到 %s 失败: %w

What it means

selectTab found the sub-tab matching the requested label, but humanize.Click on the tab element failed (xiaohongshu/user_profile.go:188). The message names the target tab label (e.g. 喜欢/收藏). The click is wrapped with humanize delays, so failure usually comes from rod's click mechanics (element detached, obscured, or page navigating).

Solutions

1. Retry the whole GetMyProfileViaSidebar call; transient re-renders usually succeed on a second pass.
2. Verify no login wall or verification dialog is blocking the page.
3. Wait longer after navigation (increase stability wait) before selecting the tab.
4. If persistent, re-check the tab element selector against current XHS markup.

Example fix

// before
resp, err := action.GetMyProfileViaSidebar(ctx, tab)
// after
var resp *xiaohongshu.UserProfileResponse
err := retry.Do(3, func() error {
    r, e := action.GetMyProfileViaSidebar(ctx, tab)
    resp, err = r, e
    return e
})

var resp *UserProfileResponse
err := retry.Do(3, func() error {
    r, e := action.GetMyProfileViaSidebar(ctx, tab)
    resp = r
    return e
})

When it happens

Trigger: Calling GetMyProfileViaSidebar(ctx, tab) with a non-default tab where the matching `.reds-tab-item` element becomes detached or unclickable between listing and clicking — a re-render replaced the node, an overlay intercepts the click, or the page navigated.

Common situations: XHS re-rendered the tab bar right before the click; anti-bot overlay/interstitial on top; slow page causing staleness; browser tab closed by user or timeout.
