What causes "cole o link do vídeo do Bilibili" in tonhowtf/omniget?

Validate/require a non-empty URL in the UI before invoking export

cole o link do vídeo do Bilibili

Error message

cole o link do vídeo do Bilibili

What it means

export::run trims opts.url and throws 'cole o link do vídeo do Bilibili' when the result is empty. This is a required-input guard: the export pipeline needs a Bilibili video URL before it can fetch cookies and danmaku.

Solutions

Validate/require a non-empty URL in the UI before invoking export
Check that the field binding actually passes the user's input into ExportOptions.url
In callers, bail early with a clear message when url.trim().is_empty()

Example fix

// before
export::run(&ExportOptions { url: form.url, ..opts }).await?;
// after
anyhow::ensure!(!form.url.trim().is_empty(), "informe o link do vídeo");
export::run(&ExportOptions { url: form.url.clone(), ..opts }).await?;

Defensive patterns

Strategy: validation

Validate before calling

fn url_present(url: &str) -> bool {
    !url.trim().is_empty()
}

Try / catch

match export::run(&opts, &progress).await {
    Err(e) if e.to_string().contains("cole o link") => focus_url_input_and_prompt_user(),
    Err(e) => propagate(e)?,
    Ok(res) => use_result(res),
}

Prevention

Disable the export button until the URL field is non-empty
Trim inputs at the UI boundary before constructing ExportOptions
Validate required fields in one place before calling pipeline stages

When it happens

Trigger: Calling bilibili::danmaku::export::run with ExportOptions { url: "" } or a whitespace-only string; the frontend bound an empty input field.

Common situations: User clicked export before pasting a link; form state reset to empty string; a previous pipeline step produced an empty URL variable.
