What causes "Nenhum URL de imagem" in tonhowtf/omniget?

Re-fetch media info; transient parser/CDN issues may resolve

Nenhum URL de imagem

Error message

Nenhum URL de imagem

What it means

native_download fails when the Reddit media info has an empty available_qualities list for a Photo post. `.first()` returns None, so the code short-circuits with this anyhow error instead of panicking. It indicates Reddit returned metadata but no downloadable image URL/quality entries.

Solutions

Re-fetch media info; transient parser/CDN issues may resolve
Verify the post URL is a real photo post and still publicly available
Update the Reddit scraper/parser to handle the current Reddit response shape
Check logs of available_qualities for the post to confirm it is genuinely empty

Example fix

let quality = info.available_qualities.first().ok_or_else(|| anyhow!("Nenhum URL de imagem"))?;
// after (with fallback)
let quality = info.available_qualities.first().with_context(|| format!("Nenhum URL de imagem para post {}", info.title))?;

Defensive patterns

Strategy: validation

Validate before calling

if info.available_qualities.is_empty() {
    return Err(format!("post '{}' has no downloadable image qualities", info.title));
}

Prevention

Check available_qualities is non-empty before calling native_download for photos
Validate media info right after parsing, not at download time
Log parsed qualities to detect parser regressions early

When it happens

Trigger: Downloading a Reddit photo post whose info resolution succeeded but produced no qualities (e.g. deleted/removed media, gallery item stripped, or parser failed to extract any format entries).

Common situations: Posts removed by moderators, images hosted on a CDN that returned an error page parsed as valid info, or Reddit API shape changes that leave available_qualities empty.

Understand the failure class

Background: EmptyResultError / "no results found": when an API or scraper succeeds but returns zero rows — this error's family across 9 libraries.
