No gallery URL available

Error message

No gallery URL available

What it means

gallery-dl-based `download` extracts the gallery URL from the first entry of `available_qualities` and errors when the list is empty. The gallery-dl binary needs a target URL, so without one the download cannot start.

Solutions

1. Re-run gallery info extraction to repopulate available_qualities before downloading.
2. Verify the gallery URL extraction covers the specific site supported by gallery-dl.
3. If the info step cannot populate URLs, construct MediaInfo directly from the user-supplied gallery URL.
4. Update gallery-dl (`gallery-dl -U` or re-fetch) if site changes break extraction and leave the list empty.

Example fix

// before
let url = info.available_qualities.first().map(|q| q.url.clone()).ok_or_else(|| anyhow!("No gallery URL available"))?;
// after
let url = info
    .available_qualities
    .first()
    .map(|q| q.url.clone())
    .or_else(|| info.source_url.clone())
    .ok_or_else(|| anyhow!("No gallery URL available (qualities empty)"))?;

// Rust, before calling download
if info.available_qualities.iter().all(|q| q.url.is_empty()) {
    return Err(anyhow!("Gallery info carries no URL; re-extract gallery info"));
}

When it happens

Trigger: Calling gallerydl `download` with MediaInfo whose `available_qualities` vec is empty — i.e. the gallery info step produced no URL entries.

Common situations: Gallery resolution succeeded partially (metadata found but no URL captured), unsupported gallery sites where URL extraction yields nothing, or stale MediaInfo reused after the original gallery page changed.

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.
