HTTP ${response.status}

Error message

HTTP ${response.status}

What it means

#fetchCityPage performs fetch(url) and throws 'HTTP <status>' when response.ok is false (any status outside 200–299). It surfaces the HTTP status of a failed city-page XML request so the caller sees the server's rejection code via the provider's error callback.

Solutions

1. Check the status code in the error: 404 → verify siteCode/provCode form a valid URL; 403 → check for IP blocking; 5xx → retry later
2. curl the constructed index/city URL and inspect the response
3. Confirm network/proxy allows requests to weather.gc.ca
4. The provider's fetcher timer will retry on the next interval — verify it recovers after upstream heals

Example fix

// before
{ siteCode: "s0009999", provCode: "ZZ" } // 404
// after
{ siteCode: "s0000458", provCode: "ON" } // 200

const url = /* construct the same city-page URL the provider builds */;
const pre = await fetch(url);
if (!pre.ok) console.warn(`EC endpoint unhealthy: HTTP ${pre.status} — fix siteCode/provCode or wait for recovery`);

provider.setCallbacks(
  (data) => render(data),
  (err) => {
    const m = /^HTTP (\d+)$/.exec(err.message || "");
    if (m) {
      const status = Number(m[1]);
      if (status === 404) fixSiteConfig();
      else if (status >= 500 || status === 429) retryWithBackoff();
    }
  }
);

When it happens

Trigger: Environment Canada returns 404 for a bad siteCode/provCode URL, 403 (blocked/rate limited), 5xx server error, or 301/redirect handled as non-ok.

Common situations: Wrong siteCode producing a dead URL; EC service outage; corporate proxy blocking the request; network change mid-session.
