Youdao note extractor returned a malformed payload

Error message

Youdao note extractor returned a malformed payload

What it means

CommandExecutionError thrown by normalizeExtractionResult when the payload returned by the in-page extractor is not an array (even after unwrapEvaluateResult unwraps {session,data} envelopes). The extractor contract requires [ok, ...fields]; anything else means the page runtime changed or evaluate returned something unexpected, so the library cannot interpret the result.

Solutions

1. Retry the command; transient SPA navigation or hydration timing can corrupt the evaluate result
2. Update the CLI/library to the latest version in case the extractor was patched for Youdao page changes
3. Increase post-load wait before evaluate (the command already waits ~2s) or reduce extension interference by running with a clean browser profile
4. Inspect the raw payload (log it) to see what shape evaluate actually returned and report it upstream

function isExtractorPayload(p) {
  const data = p && !Array.isArray(p) && typeof p === 'object' && 'data' in p ? p.data : p;
  return Array.isArray(data);
}

try {
  await youdaoNote(url);
} catch (e) {
  if (String(e.message).includes('malformed payload')) {
    // retry once, then surface 'youdao page structure changed' to the operator
  } else throw e;
}

When it happens

Trigger: page.evaluate returning an object/string instead of the IIFE's array (browser extension interference, a page navigation replacing the document mid-evaluate, a wrapper runner returning its own envelope with an unexpected shape, or evaluate serializing a promise/error object).

Common situations: Youdao shipping a new page framework that breaks the injected script; headless browser plugins injecting scripts that alter evaluate return values; SPA re-render/navigation between goto and evaluate; automation runners that wrap evaluate results in custom envelopes unwrapEvaluateResult doesn't recognize.
