Error message

{}

What it means

After running yt-dlp in JSON mode, `ytdlp_json` scans stdout for a line starting with '{'. If none is found, it treats the run as failed and raises an error whose message is the shortened stderr reason (via `short_reason`). This surfaces yt-dlp's own failure output (e.g. video unavailable, login required) as the error.

Solutions

  1. Read the `{}` message: it is the shortened stderr from yt-dlp; fix the cause it names (URL, login, network).
  2. Update yt-dlp to the latest version (`yt-dlp -U` or pip install -U yt-dlp) — TikTok extractors change often.
  3. Verify the video URL opens in a browser and is public.
  4. If cookies/session are required, pass the session cookie file to yt-dlp.

Example fix

// before
$ yt-dlp -j https://www.tiktok.com/@u/video/123
ERROR: video unavailable
// after
$ yt-dlp -U   # update extractors, then retry with a valid public URL
Defensive patterns

Strategy: try-catch

Validate before calling

// Validate the URL shape before invoking yt-dlp
if !url.contains("tiktok.com") { return Err(anyhow!("URL não parece ser do TikTok")); }

Try / catch

match ytdlp_json(&args).await {
    Ok(v) => Ok(v),
    Err(e) if e.to_string().contains("unavailable") => warn_user_and_skip(),
    Err(e) => { update_ytdlp().await; Err(e) },
}

Prevention

When it happens

Trigger: yt-dlp exits with no JSON on stdout — unsupported/removed video, network failure, age/login restriction, bad URL, or a yt-dlp version whose output format changed; stdout is empty while stderr carries the reason.

Common situations: Private or region-blocked TikTok video; yt-dlp outdated for a changed TikTok page structure; bot-check/captcha page returned instead of media; invalid or malformed URL passed in.
