Mobile stream ticket was unavailable

Error message

Mobile stream ticket was unavailable

What it means

refreshStreamTicket fetches a new stream ticket via POST /__codewhale/mobile/stream-ticket and validates the result. If the response is empty or `stream_ticket` is not a string, the runtime cannot resume/authenticate the event stream, so it throws.

Solutions

1. Retry refreshStreamTicket(); transient backend errors often resolve.
2. Check the Runtime version serving the page matches the endpoint's response schema.
3. Inspect the endpoint's raw response (curl with the same auth) to see what is actually returned.

Example fix

// before
const ticket = await refreshStreamTicket();
// after
let ticket;
try { ticket = await refreshStreamTicket(); }
catch (e) { ticket = await refreshStreamTicket(); /* retry once */ }

if (result && typeof result.stream_ticket !== 'string') {
  throw new Error('bad ticket payload');
}

function hasStreamTicket(r) {
  return !!r && typeof r.stream_ticket === 'string' && r.stream_ticket.length > 0;
}

try {
  ticket = await refreshStreamTicket();
} catch {
  await new Promise((r) => setTimeout(r, 500));
  ticket = await refreshStreamTicket();
}

When it happens

Trigger: The stream-ticket endpoint returns 204/null, a body without `stream_ticket`, or a non-string ticket value (server schema change or backend failure).

Common situations: Runtime backend failing to mint tickets; version mismatch between mobile page and server response shape; transient server error already surfaced through api() and a malformed fallback body.
