o post não veio na resposta (apagado, privado ou id errado)

Error message

o post não veio na resposta (apagado, privado ou id errado)

What it means

fetch_post requests the Reddit post JSON listing and navigates the pointer /0/data/children/0/data; if that path is absent the post is not retrievable, and the error explains the usual causes: deleted post, private post, or wrong id. It's a guard against Reddit returning an empty children array or an unexpected envelope instead of failing with a cryptic None later.

Solutions

Verify the post id/URL in a browser — confirm the post still exists and is public
Check the id format (Reddit base-36 id, no URL-encoding issues)
Retry later if Reddit returned an empty listing transiently (rate limit/edge error)
Handle authentication if the post requires login to view

Example fix

// before: blind fetch
let post = fetch_post(&fetcher, id).await?;
// after: validate id shape first
if id.len() < 4 || !id.chars().all(|c| c.is_ascii_alphanumeric()) {
    return Err(anyhow!("id de post inválido: {}", id));
}
let post = fetch_post(&fetcher, id).await?;

Defensive patterns

Strategy: validation

Validate before calling

fn looks_like_reddit_id(id: &str) -> bool {
    (4..=12).contains(&id.len())
        && id.chars().all(|c| c.is_ascii_alphanumeric())
}

Try / catch

match run(&args).await {
    Err(e) if e.to_string().contains("o post não veio") => {
    eprintln!("post apagado/privado ou id errado: {e}");
    }
    other => other?,
}

Prevention

Validate the post id/URL format before calling
Verify the post opens publicly in a browser before automating downloads
Treat empty Reddit listings as possibly transient and retry once

When it happens

Trigger: Calling the reddit download run flow with a post id that doesn't exist, was deleted/removed by moderators, is in a private/quarantined subreddit, or a malformed id that yields an empty listing.

Common situations: Typos in the post id, post removed since link was saved, subreddit gone private, Reddit rate-limiting/edge returning an empty listing for valid ids.

Understand the failure class

Background: "Not found" and "does not exist" errors: why "Task not found", "No such folder", and "Can't find" fire when a lookup comes back empty — this error's family across 14 libraries.
