xAI: resposta invalida

Error message

xAI: resposta invalida ({})

What it means

ask_xai() called the xAI API and the HTTP response body could not be deserialized as JSON, so the serde error is wrapped into this message. This indicates the xAI endpoint (or a proxy) returned non-JSON content such as an HTML error page or an empty body.

Solutions

1. Verify the xAI API base URL includes the correct path (https://api.x.ai/v1).
2. Capture and log resp.text() before parsing to see the actual payload.
3. Retry on transient gateway errors (502/503 pages are HTML).
4. Check for proxy/VPN interference and network reachability to api.x.ai.

Example fix

// before
let v: Value = resp.json().await
    .map_err(|e| anyhow!("xAI: resposta invalida ({})", e))?;
// after
let text = resp.text().await?;
let v: Value = serde_json::from_str(&text)
    .map_err(|e| anyhow!("xAI: resposta invalida ({}) corpo: {:.200}", e, text))?;

// preflight da URL e da chave
let base = std::env::var("XAI_BASE_URL").unwrap_or_else(|_| "https://api.x.ai/v1".into());
if !base.starts_with("https://api.x.ai") {
    eprintln!("aviso: base URL incomum para xAI: {base}");
}

match grok::ask(prompt).await {
    Ok(a) => a,
    Err(e) if e.to_string().starts_with("xAI: resposta invalida") => {
        tokio::time::sleep(Duration::from_secs(3)).await;
        grok::ask(prompt).await // gateway pages are usually transient
    }
    Err(e) => Err(e),
}

When it happens

Trigger: xAI's chat endpoint returns HTML/empty/non-JSON (gateway timeout page, wrong base URL pointing at a website, proxy interception) during the ask flow.

Common situations: Misconfigured XAI base URL (e.g. missing /v1 or pointing to the console site); corporate proxy or captive portal; xAI outage serving non-JSON errors; response stream truncated mid-body.

Understand the failure class

Background: "Invalid JSON response" and "Failed to parse response" errors: when an API answers 200 but the body isn't the JSON your library expected — this error's family across 28 libraries.
