Error message

Manus ${label} failed: ${value.message || value.__error}

What it means

CommandExecutionError thrown by requireObject() when the payload carries __error — an in-page/application-level failure that was not an HTTP status error — with the server's message surfaced after 'Manus <label> failed:'.

Solutions

1. Read the trailing message for the root cause and retry if transient.
2. Verify connectivity/proxy settings for the browser the CLI drives.
3. Re-login in the browser in case the failure is session-related.
4. Update the CLI if Manus changed its internal API/front-end.

function isInPageError(v) { return v != null && typeof v === 'object' && v.__error !== undefined; }

try {
  const data = await manusData();
} catch (e) {
  if (/Manus .* failed:/.test(e.message) && !/HTTP \d{3}/.test(e.message)) {
    console.error('In-page request failed:', e.message, '— check connectivity and re-login');
  } else throw e;
}

When it happens

Trigger: The injected script catches an exception while calling Manus's API (fetch rejection, JSON parse failure, script-level error) and returns {__error: ...} instead of data.

Common situations: Network interruption mid-request from the browser context, CORS or CSP blocking the in-page fetch, Manus front-end bundle changes breaking the injected call, DNS/proxy failures.
