The structuredClone function in JavaScript behaves differently in Node.js and web browsers when cloning a Blob object with the transfer option. In Node.js, the Blob is cloned successfully, while in web browsers, a DataCloneError is thrown. This discrepancy is causing the web platform tests in #54468 to fail.

const blob = new Blob();
console.log(structuredClone(blob, { transfer: [blob] }));
  • Node.js Behavior: Successful cloning of the Blob
  • Web Browser Behavior: Uncaught DataCloneError: Failed to execute 'structuredClone' on 'Window': Value at index 0 does not have a transferable type.
