Error message

informe o seu usuário do Medium (ou capture os cookies de medium.com no gerenciador para incluir os rascunhos)

What it means

After collecting documents, if none were found (e.g. the authenticated session listing yielded nothing), run() falls back to fetching the public RSS feed, which requires a Medium username. When opts.user is empty at that point, it cannot build the feed URL and throws this error.

Solutions

Set opts.user to your Medium username before calling run()
Capture valid medium.com cookies in the session manager so from_session can list stories and the fallback is not needed
Verify the username field is populated in the UI/config that builds Options

Example fix

// before
let opts = Options { user: "".into(), ..Default::default() };
// after
let opts = Options { user: "someuser".into(), ..Default::default() };

Defensive patterns

Strategy: validation

Validate before calling

if opts.user.trim().is_empty() {
    return Err(anyhow!("informe o usuário do Medium antes de exportar"));
}

Try / catch

match run(&opts, progress).await {
    Err(e) if e.to_string().contains("usuário do Medium") => prompt_user_for_username(),
    other => other?,
}

Prevention

Make the username field required in the UI when no session cookies are present
Trim and validate opts.user when constructing Options
Persist the last used username in config

When it happens

Trigger: Calling run() with an empty opts.user AND the Medium session (cookies) returned no documents (docs.is_empty()), so the RSS-feed fallback path needs a username that is missing.

Common situations: User expected cookies alone to be enough but session listing failed silently (e.g. expired session, drafts-only scope); Options built from an empty settings form; typo causing user to be trimmed to empty.
