What causes "youkuData.Data.Error.Note" in iawia002/lux?

Pass a real browser session cookie containing cna=... via extractors.Options.Cookie

youkuData.Data.Error.Note

Error message

youkuData.Data.Error.Note

What it means

The Youku extractor calls youkuUps(vid, option), which resolves a utid from the 'cna' cookie (or fetches one) and queries ups.youku.com get.json with ccode/ckey parameters. If the UPS response carries Data.Error.Code != 0, Youku's own ErrorMsg/Note becomes the error. It means the whole exchange succeeded but Youku refused to hand out stream data for this vid.

Solutions

Pass a real browser session cookie containing cna=... via extractors.Options.Cookie
Override the ccode/ckey via the YoukuCcode and YoukuCkey options (CLI flags --youku-ccode / --youku-ckey) with values captured from a working browser session
Confirm the video plays on v.youku.com in a browser from the same network and without VIP if it is member content
If ErrorNote says the video does not exist, drop the URL; if it mentions rights/region, use an appropriate network

Example fix

// before
options := extractors.Options{} // no cookie, default ccode/ckey
_, err := youku.Extract(url, options)

// after
options := extractors.Options{
    Cookie:     "cna=YOUR_CNA_FROM_BROWSER; ...",
    YoukuCcode: "0510",
    YoukuCkey:  "YOUR_CAPTURED_CKEY",
}
_, err := youku.Extract(url, options)

Defensive patterns

Strategy: try-catch

Try / catch

_, err := youku.Extract(url, opts)
if err != nil {
    if strings.Contains(err.Error(), "ckey") || strings.Contains(err.Error(), "版权") || strings.Contains(err.Error(), "地区") {
        // auth/geo refusal: refresh cna cookie + ccode/ckey options, retry once
        opts.Cookie = freshCookie()
        opts.YoukuCkey = freshCkey()
        _, err = youku.Extract(url, opts)
    }
    return err
}

Prevention

Keep a valid browser cna cookie and pass it via Options.Cookie
Capture ccode/ckey from a working browser session when the built-in pair starts failing
Skip member-only and region-locked titles unless you hold the right session/network

When it happens

Trigger: Missing or stale cna cookie so the utid sent to UPS is empty/invalid; the default YoukuCcode/YoukuCkey combination being rejected by UPS; deleted or copyright-removed videos; region-restricted content; member-only videos requested without a VIP session.

Common situations: Running without any Youku cookies; Youku rotating ckey requirements so the built-in pair stops working; non-mainland IPs being denied certain titles. This is the classic lux+Youku failure mode and usually needs fresh cookies/options.
