a conta não devolveu nenhuma linha

Error message

a conta não devolveu nenhuma linha

What it means

After fetching all requested lists via get_all and merging parsed entries, run() checks whether anything was collected; an empty result is treated as an error rather than producing an empty export. It guards against silently writing empty JSON/CSV files.

Solutions

Verify on trakt.tv that the account/lists actually contain items
Check the list names/slugs requested in opts match real lists for the user
Confirm pagination headers were honored — try increasing opts.max_pages
Log the raw get_all response per list to see which one returned empty
Handle the empty case in the caller by showing a friendly message instead of treating it as a crash

Defensive patterns

Strategy: try-catch

Validate before calling

// pre-check that the account has at least one list with items
let lists = trakt_get_user_lists(&config).await?;
if lists.iter().all(|l| l.item_count == 0) {
    return Err("nothing to export: all lists are empty");
}

Try / catch

if let Err(e) = trakt_lists::run(&opts, &progress).await {
    if e.to_string().contains("nenhuma linha") {
        // show 'nothing to export' notice instead of a failure dialog
        return Ok(());
    }
    return Err(e);
}

Prevention

Verify list names/slugs exist and contain items before exporting
Confirm the account is the intended one and is not empty
Cap max_pages consistently with actual list sizes

When it happens

Trigger: Every list path in the requested set returned zero items — e.g. the account's lists are all empty, all requested list slugs don't exist, or get_all parsed no recognizable entries (parse_items matched nothing).

Common situations: New Trakt account with empty watchlist/lists; requesting a custom list by a name that doesn't exist for this user; account is private/empty; API returned success but empty arrays due to a pagination edge case.

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.
