unexpected status code

Error message

unexpected status code %d

What it means

The Digitalyama source, when the API responds with a non-success status code, tries to decode a structured error body ({detail: [{msg, type}]}). If that decode itself fails, it falls back to emitting fmt.Errorf("unexpected status code %d", resp.StatusCode) — a plain HTTP status error.

Solutions

  1. Check/fix the Digitalyama API key in the provider config
  2. Confirm the status code context: 401/403 → credentials, 429 → backoff and slow down, 5xx → retry later
  3. Ensure no proxy/WAF is altering responses for the endpoint
  4. Retry with backoff or disable the digitalyama source temporarily
Defensive patterns

Strategy: try-catch

Try / catch

for result := range results {
    if result.Type == subscraping.Error {
        gologger.Warning().Msgf("digitalyama: %v", result.Error)
        continue
    }
    // process result
}

Prevention

When it happens

Trigger: Digitalyama API returns an unexpected status code whose body is not the documented error shape (undecodable JSON) — auth failures, rate limiting, outages, proxies returning HTML error pages.

Common situations: Invalid/missing Digitalyama API key; hitting request quotas; a proxy or WAF intercepting the request and returning non-JSON; Digitalyama service disruption.
