unexpected status code %d for %s, response: %s

Error message

unexpected status code %d for %s, response: %s

What it means

The XML twin of the JSON helper (decodeXmlFromRequest): status was not 200, and the error includes the status code, URL, and a 256-byte body snippet. Used for RSS/Atom-style feeds such as the videos widget's YouTube feeds.

Solutions

1. Inspect the status code and body snippet: 404 means a bad/deleted channel or playlist ID, 429 means back off
2. Correct the channel/playlist IDs in the videos widget configuration
3. Increase the widget's cache time so feeds are fetched less often

func isUnexpectedStatus(err error) bool {
	return err != nil && strings.Contains(err.Error(), "unexpected status code")
}

feed, err := decodeXmlFromRequest[ T ](client, req)
if err != nil && isUnexpectedStatus(err) {
    // 404: drop the bad feed from config; 429/5xx: retry with backoff
    slog.Warn("feed fetch failed", "url", req.URL.String(), "err", err)
}

When it happens

Trigger: A feed URL returning non-200: 404 for a deleted channel/playlist ID, 429 from YouTube feed throttling, 403 from an IP block, or 5xx from the feed host.

Common situations: A YouTube channel ID in the videos config is wrong or the channel was removed; a self-hosted RSS host blocks the server's IP; too frequent polling of the same feeds.
