HTTP GET %s: status %d

Error message

HTTP GET %s: status %d

What it means

fetchSkillPresetsFromURL throws this when the HTTP response completes but the status code is not 200 OK. It is a non-2xx guard: 404 for a moved presets file, 403 for blocked access, 5xx for server trouble — the status is embedded in the message along with the URL.

Solutions

1. Check the logged status code: 404 → update the URL to the current presets location; 403 → check auth/UA requirements; 5xx → retry later
2. curl -I the URL to confirm the status outside the app
3. Replace the dead source with a maintained mirror; with multiple sources configured, fetch succeeds if any one returns 200
4. If the source requires a token, switch to a source URL that includes authorized access

Example fix

// before
url = "https://example.com/skills-presets-v1.json"   // 404
// after
url = "https://example.com/skills-presets-v2.json"   // verify: curl -I returns 200

resp, err := http.Head(sourceURL)
if err == nil && resp.StatusCode != http.StatusOK {
    return fmt.Errorf("presets source unhealthy: %s returns %d", sourceURL, resp.StatusCode)
}

presets, err := fetchSkillPresetsFromURL(url, timeout)
if err != nil {
    var statusErr interface{ Error() string }
    if strings.Contains(err.Error(), "status ") { // e.g. "HTTP GET ...: status 404"
        slog.Warn("presets source returned non-200; trying next source", "url", url, "err", err)
    }
    _ = statusErr
}

When it happens

Trigger: GETting a skill presets URL that returns 404 (file renamed/moved), 403 (rate limit, geo/UA block, missing auth), 301/302 that Go followed to a non-200 endpoint, or 5xx during a server incident.

Common situations: Preset source URL pinned to an old version path that no longer exists; CDN blocking the default Go User-Agent; mirror returning 503 under load.
