openrouter video non-JSON: ${truncate(submitText, 200)}

Error message

openrouter video non-JSON: ${truncate(submitText, 200)}

What it means

Thrown when the video submit endpoint returned HTTP 2xx but JSON.parse failed on the body. OpenRouter's async video submit is contractually JSON (carrying id and polling_url); a non-JSON 2xx means an interceptor rewrote the response or baseUrl is misrouted to a host returning HTML.

Solutions

1. Inspect the truncated body in the error — HTML/doctype tags indicate interception/misroute.
2. Reset credentials.baseUrl to the default or remove it.
3. Whitelist openrouter.ai through any HTTP proxy.
4. Retry once for transient interstitials.

Example fix

// before
try { submitData = JSON.parse(submitText); }
catch { throw new Error(`openrouter video non-JSON: ${truncate(submitText, 200)}`); }

// after — distinguish HTML interception
try { submitData = JSON.parse(submitText); }
catch {
  const html = /<html|<!doctype/i.test(submitText);
  throw new Error(
    `openrouter video ${html ? 'returned HTML (interception?)' : 'non-JSON'}: ${truncate(submitText, 200)}`,
  );
}

function looksLikeHtmlBody(text: string): boolean {
  return /<html|<!doctype|<title>/i.test(text.slice(0, 200));
}

if (looksLikeHtmlBody(submitText)) {
  throw new Error(`openrouter video submit returned HTML (proxy/interception or wrong baseUrl): ${truncate(submitText, 200)}`);
}

function isJsonContentType(resp: Response): boolean {
  const ct = resp.headers.get('content-type') || '';
  return ct.includes('application/json') || ct.includes('+json');
}

try {
  submitData = JSON.parse(submitText);
} catch {
  if (looksLikeHtmlBody(submitText)) {
    throw new Error(`openrouter video returned HTML (interception?): ${truncate(submitText, 200)}`);
  }
  throw new Error(`openrouter video non-JSON: ${truncate(submitText, 200)}`);
}

When it happens

Trigger: Proxy/CDN served an HTML page with 200, baseUrl points at a wrong host, or a captive portal intercepted the request. The guard stops the subsequent id/polling_url extraction from running on non-JSON input.

Common situations: Corporate proxy blocking openrouter.ai with an HTML block page, baseUrl typo hitting a parked/marketing domain, or a transient CDN interstitial.
