Doubao blocked the request with a verification challenge

Error message

Doubao blocked the request with a verification challenge

What it means

After submitting the message, sendDoubaoMessage runs detectDoubaoVerificationScript(); if Doubao presented an anti-bot/verification challenge, this CommandExecutionError is thrown with the detected signal as detail. The send did not complete as expected because Doubao is requiring human verification.

Solutions

Complete the verification challenge manually in the browser, then retry
Slow down message rate and add delays between sends
Use a normal browser profile with established Doubao cookies
Switch network/IP if the current one is flagged

Example fix

// before
const verification = await page.evaluate(detectDoubaoVerificationScript());
if (verification?.detected) throw new CommandExecutionError('Doubao blocked the request with a verification challenge', ...);
// after
const verification = await page.evaluate(detectDoubaoVerificationScript());
if (verification?.detected) {
  await pauseForHumanVerification(page); // waits until challenge dismissed
}
const recheck = await page.evaluate(detectDoubaoVerificationScript());
if (recheck?.detected) throw new CommandExecutionError('Doubao blocked the request with a verification challenge');

Defensive patterns

Strategy: try-catch

Validate before calling

const v = await page.evaluate(detectDoubaoVerificationScript());
if (v?.detected) throw new Error('Resolve the Doubao challenge before sending messages');

Try / catch

try {
  await sendDoubaoMessage(page, text);
} catch (e) {
  if (/verification challenge/.test(e.message)) {
    await promptUserToSolveChallenge(page); // block until human resolves
    await sendDoubaoMessage(page, text);
  } else throw e;
}

Prevention

Throttle message rate to avoid risk control
Use a persistent, cookie-warmed browser profile
Detect challenges proactively before each send
Avoid datacenter IPs that trigger Doubao risk control

When it happens

Trigger: detectDoubaoVerificationScript() returns {detected:true} right after pressing Enter/clicking send — captcha iframe, slider challenge, or risk-control banner appears in the page.

Common situations: Account/IP flagged for automation; too many rapid messages; fresh browser profile without cookies; datacenter IP triggering risk control.
