Fix DataCloneError

in Node.js

Solution

The DataCloneError in Node.js typically arises when attempting to transfer non-transferable objects (like functions, class instances, or objects containing them) across realms, such as using `postMessage` to communicate between a web worker and the main thread or when cloning objects for caching. To resolve this, ensure you are only transferring plain JavaScript objects or explicitly serializable data (like JSON-compatible types) by stripping out problematic properties or manually reconstructing the necessary data on the receiving end. Consider using structured cloning alternatives or custom serialization if you need to transfer complex data and direct transfer is not possible.
