What causes "chunk de assinatura do X nao encontrado" in tonhowtf/omniget?

Check network access and whether the probe requests are being blocked (403/429 from X).

chunk de assinatura do X nao encontrado

Error message

chunk de assinatura do X nao encontrado

What it means

indices probes candidate URLs to locate X's signing chunk JS file, fetches it, and extracts signature index constants via the regex r"\(\w\[(\d{1,2})\],\s*16\)". If no candidate URL could be resolved, it throws "chunk de assinatura do X nao encontrado". Without this chunk the txid signature indices cannot be computed.

Solutions

Check network access and whether the probe requests are being blocked (403/429 from X).
Update the URL-probing logic to match X's current HTML/JS bundle layout.
Capture the probed responses and confirm at least one returns parseable HTML containing the chunk link.
Retry later — this often resolves when X finishes a frontend deploy or the rate limit clears.

Defensive patterns

Strategy: retry

Try / catch

match create(...).await {
    Ok(v) => v,
    Err(e) if e.to_string().contains("chunk de assinatura") => {
        eprintln!("chunk do X não resolvido; atualizando parser ou aguardando deploy");
        // retry later or fall back to cached indices
    }
    Err(e) => return Err(e),
}

Prevention

Cache the last working chunk URL and indices as a fallback
Monitor X frontend deploys; update probing logic promptly
Check probe responses for 403/429 before concluding the chunk is gone
Pin a known-good offline copy of the chunk as last resort

When it happens

Trigger: Calling create when all probed URLs fail (network errors, HTML without the chunk script link, or X renaming/moving the chunk asset) so `url` stays None.

Common situations: X deploying a new main.js bundle layout; request blocked or rate-limited so no candidate page loads; offline/proxy environments; X changing how the chunk URL is embedded in the HTML.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
