Error message

a conta logada não tem nenhuma assinatura ativa (ou a sessão expirou)

What it means

After successfully calling the authenticated /api/v1/subscriptions endpoint, discover parses the payload with parse_subscriptions. If the parsed subscription list is empty it raises this error, meaning either the account genuinely has no active subscriptions or the session cookies are stale/expired so the API returned an empty/degraded payload.

Solutions

Re-capture fresh substack.com cookies in the cookie manager (re-login first) and retry
Verify the account actually has subscriptions by visiting substack.com while logged in
If the account truly has none, provide the publications manually instead of using discover

Example fix

// before
let subs = substack::discover(&fetcher).await?;
// after
let subs = match substack::discover(&fetcher).await {
    Ok(s) => s,
    Err(e) if e.to_string().contains("assinatura") => relogin_and_retry(&mut fetcher)?,
    Err(e) => return Err(e),
};

Defensive patterns

Strategy: try-catch

Try / catch

match substack::discover(&fetcher).await {
    Ok(subs) if !subs.is_empty() => subs,
    Ok(_) => Vec::new(), // treat as expired session
    Err(e) if e.to_string().contains("assinatura") => {
        refresh_cookies(&mut fetcher)?;
        substack::discover(&fetcher).await?
    }
    Err(e) => return Err(e),
}

Prevention

Detect empty subscription payloads early and refresh cookies proactively
Cache subscription lists to notice when a previously non-empty result turns empty
Verify session validity with a lightweight authenticated endpoint before bulk operations

When it happens

Trigger: discover() is called with a valid-looking session, the request succeeds, but parse_subscriptions(&v) yields zero entries — logged-in account with no paid/free subscriptions, or expired cookies causing an empty subscriptions array.

Common situations: Fresh Substack account with no subscriptions; cookies captured weeks ago and since invalidated by re-login; subscription list filtered out entirely by the parser after a Substack API shape change.

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.
