Ctrip bus page did not render schedule rows

Error message

Ctrip bus page did not render schedule rows (state=${String(waitResult)})

What it means

The bus page load is considered successful only when WAIT_FOR_BUS_JS returns 'content'. Any other state (timeout, unknown selector state, navigation failure) means schedule rows never rendered, and the CLI throws CommandExecutionError including the raw state for debugging.

Solutions

1. Rerun the command — transient slow loads often succeed on retry
2. Check the `state=` value in the message and compare against the states WAIT_FOR_BUS_JS can return
3. Increase the wait timeout inside WAIT_FOR_BUS_JS if your network is slow
4. Update the wait script's selectors after a Ctrip DOM change

Example fix

// before
const waitResult = await page.evaluate(WAIT_FOR_BUS_JS);
// after (example: extend timeout in WAIT_FOR_BUS_JS)
const waitResult = await page.evaluate(WAIT_FOR_BUS_JS, { timeoutMs: 30000 });

  if (e instanceof CommandExecutionError && e.message.includes('did not render schedule rows')) {
    const state = /state=(\S+)/.exec(e.message)?.[1];
    console.error(`Bus page wait failed (state=${state}); retrying with backoff`);
    await sleep(3000);
    rows = await ctripBusList({ from, to, date });
  } else {
    throw e;
  }
}

When it happens

Trigger: `clis ctrip bus` where page.evaluate(WAIT_FOR_BUS_JS) returns anything other than 'captcha' or 'content' — e.g. a wait timeout, an error state string, or Ctrip serving a layout the wait script does not recognize.

Common situations: Slow network causing the wait script's timeout to fire; Ctrip DOM/A-B test redesign so expected schedule selectors never appear; page redirected to an interstitial or error page.
