arquivo vazio

Error message

arquivo vazio

What it means

fetch_one() bails with "arquivo vazio" when the HTTP response succeeds (2xx) but the downloaded body has zero bytes. The library refuses to write empty image files, so a 200-with-empty-body (usually a broken CDN response or wrong content negotiation) surfaces as this error instead of silently creating a 0-byte image.

Solutions

1. Retry the download — empty-200 responses are often transient CDN issues (and 429/5xx already retry internally, this case does not).
2. Delete the partially-downloaded emote set and re-run to refresh URLs from the provider API.
3. Check proxy/antivirus interference if many downloads come back empty.
4. Verify the URL manually; if consistently empty, treat that emote as unavailable and skip it.

let mut attempt = 0;
loop {
    match emotes::run(&opts, &progress).await {
        Err(e) if e.to_string().contains("arquivo vazio") && attempt < 2 => {
            attempt += 1;
            tokio::time::sleep(Duration::from_secs(5 * attempt)).await;
        }
        other => break other,
    }
}

When it happens

Trigger: Calling run() when an emote CDN returns HTTP 200 with an empty body: broken/empty CDN object, misconfigured proxy stripping the body, or a URL that responds 200 empty instead of 404 for deleted content.

Common situations: CDN edge serving stale empty objects; intercepting proxies/antivirus stripping bodies; provider changing image URLs so the old path now returns an empty 200.
