Error message

nao encontrei slides nessa pagina (o SlideShare pode ter mudado o HTML ou o deck e privado)

What it means

Thrown when the SlideShare page was fetched successfully (HTTP 2xx) but `parse_slide_urls(&html)` found zero image URLs in the markup. It means the scraper's HTML heuristics no longer match SlideShare's markup, or the page genuinely contains no extractable slides (private/deleted deck).

Solutions

Verify the deck is public by opening the URL in an incognito browser; if private, request access or use another deck.
Check if SlideShare changed its HTML and update `parse_slide_urls` selectors/regexes to match the current markup.
Retry later — bot-protection or transient pages can also return HTML without slide URLs.
Inspect the fetched HTML manually to confirm which case applies before changing code.

Defensive patterns

Strategy: try-catch

Try / catch

match slides::download(&url, &dest, progress).await {
    Ok(res) => use(res),
    Err(e) if e.to_string().contains("nao encontrei slides") => {
        // check deck is public / retry later / update scraper
    }
    Err(e) => return Err(e),
}

Prevention

Confirm the deck is public in an incognito browser first.
Don't rely on scraping heuristics — expect breakage after SlideShare redesigns.
Keep the scraper's parsing logic updated against current SlideShare HTML.

When it happens

Trigger: Calling `slides::download` with a valid slideshare.net URL whose HTML yields an empty slide-URL list: private decks, deleted decks, region/login-walled pages, or SlideShare HTML changes that break `parse_slide_urls`.

Common situations: Deck made private after sharing; deck deleted; SlideShare redesign changing image URL attributes; consent/cookie wall HTML returned instead of the deck; bot-protection page served to the HTTP client.

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.
