HTTP

Error message

HTTP %d

What it means

fetchDetail throws this generic status-code error when the detail endpoint returns any non-200, non-403 HTTP status (e.g. 404, 429, 500, 502). It signals an unexpected server-side or routing failure rather than a session problem; the plugin deliberately does not parse the body in this branch.

Solutions

1. Check DebugLog output for the printed status code to identify the class of failure.
2. Retry with backoff for transient 429/5xx statuses.
3. If 404, refresh search results to obtain a valid resource ID/type.
4. Check the site's availability in a browser; if down, wait and retry later.

Example fix

// before
body, statusCode, _, err := p.requestWithChallengeRetry(scraper, http.MethodGet, detailURL, "", "")
// after
body, statusCode, _, err := p.requestWithChallengeRetry(scraper, http.MethodGet, detailURL, "", "")
if err == nil && statusCode == http.StatusTooManyRequests {
    time.Sleep(retryBackoff)
    body, statusCode, _, err = p.requestWithChallengeRetry(scraper, http.MethodGet, detailURL, "", "")
}

// preflight availability check
resp, err := http.Head(siteBaseURL)
if err != nil || resp.StatusCode >= 500 { return errors.New("site unavailable") }

func isRetryableStatus(err error) bool {
  if err == nil { return false }
  var code int
  if _, e := fmt.Sscanf(err.Error(), "HTTP %d", &code); e != nil { return false }
  return code == 429 || code >= 500
}

detail, err := plugin.fetchDetail(id, typ, scraper)
if isRetryableStatus(err) {
    time.Sleep(5 * time.Second)
    detail, err = plugin.fetchDetail(id, typ, scraper)
}

When it happens

Trigger: Calling fetchDetail while the site returns a status other than 200/403: resource deleted (404), rate limiting (429), upstream maintenance (5xx), or redirects followed to an error page.

Common situations: Site under maintenance or temporarily down; too many concurrent detail fetches triggering 429; resource ID/type from stale search results that no longer exist; CDN misbehaving.
