Error message

nowcoder.com

What it means

fetchNowcoderData navigates a browser page to nowcoder.com and calls the JSON API. If the underlying fetch fails with an HTTP 401/403 status or an error message indicating 'need login' / 'not logged in', the library rethrows it as AuthRequiredError with host 'nowcoder.com', signaling that a valid logged-in Nowcoder session (cookies) is required. The message field of the error is the host string 'nowcoder.com'.

Solutions

1. Log in to https://www.nowcoder.com in the browser profile the CLI uses, then retry.
2. Refresh/re-establish the session if your cookies expired.
3. Verify the login by loading a members-only page in that profile.
4. Avoid running from IPs that trigger auth challenges (datacenter IPs) or use a normal residential connection.

Example fix

// before
// headless profile without session
nowcoder posts list  // AuthRequiredError: nowcoder.com
// after
// open the profile browser, log in at https://www.nowcoder.com, then rerun
nowcoder posts list

// pre-flight: confirm an active session exists in the CLI's browser profile
// e.g. open the profile, visit https://www.nowcoder.com, and confirm you are logged in before running commands

try {
  const posts = await nowcoderPostsList(opts);
} catch (err) {
  if (err instanceof AuthRequiredError && err.message === 'nowcoder.com') {
    console.error('Log in to www.nowcoder.com in the CLI browser profile, then retry.');
    process.exitCode = 3;
  } else throw err;
}

When it happens

Trigger: Calling a nowcoder data command while the browser profile has no valid session cookies; session expired; Nowcoder's API returns 401/403 or a 'need login' / 'not logged in' failure for the endpoint.

Common situations: Running the CLI in CI or a headless environment without first logging in; cookies expiring after a few days; IP flagged by Nowcoder triggering auth challenges; using a fresh browser profile that never logged in.
