Erro ao processar resposta do TikTok

Error message

Erro ao processar resposta do TikTok

What it means

The TikTok HTML page was fetched, but the JSON embedded in the __UNIVERSAL_DATA_FOR_REHYDRATION__ script tag could not be parsed by serde_json. This means TikTok served a page whose rehydration payload is malformed, truncated, or not JSON (e.g. a captcha/interstitial page). The library throws it instead of panicking on from_str.

Solutions

1. Wait a few minutes and retry — TikTok is likely serving an anti-bot challenge (see the companion 'TikTok is blocking requests' error).
2. Check that the URL is a canonical tiktok.com video URL (@user/video/id) rather than a share/redirect link.
3. Retry through a different IP / proxy or with fresh cookies to avoid the challenge page.
4. Fall back to the yt-dlp path (get_media_info_via_ytdlp), which does not depend on the rehydration JSON.

Example fix

// caller-side fallback
match tiktok.get_media_info(url).await {
    Ok(info) => info,
    Err(e) if e.to_string().contains("Erro ao processar resposta do TikTok") => {
        tiktok.get_media_info_via_ytdlp(url, &post_id).await?
    }
    Err(e) => return Err(e),
}

match tiktok.get_media_info(url).await {
    Err(e) if e.to_string().contains("Erro ao processar resposta do TikTok") => tiktok.get_media_info_via_ytdlp(url, &post_id).await,
    other => other,
}

When it happens

Trigger: fetch_detail receives HTML containing the __UNIVERSAL_DATA_FOR_REHYDRATION__ script tag, but serde_json::from_str fails on its contents — e.g. TikTok returned an anti-bot page, a partially-rendered SSR page, or an encoding that breaks JSON parsing.

Common situations: TikTok's bot protection serving a challenge page instead of the real video page; TikTok changing the payload shape/escaping; proxy or CDN mangling the response; rate-limiting from rapid repeated get_media_info calls.

Understand the failure class

Background: JSON parse error: "Unexpected token" / "not valid JSON" / "failed to parse" — what JSON parsers are really complaining about — this error's family across 45 libraries.
