missing transferable in transfer list

What does this code mean?

Code ERR_MISSING_TRANSFERABLE_IN_TRANSFER_LIST · An issue reported by Node.js.

Official explanation · Original text

An object that needs to be explicitly listed in the transferList argument is in the object passed to a postMessage() call, but is not provided in the transferList for that call. Usually, this is a MessagePort. In Node.js versions prior to v15.0.0, the error code being used here was ERR_MISSING_MESSAGE_PORT_IN_TRANSFER_LIST. However, the set of transferable object types has been expanded to cover more types than MessagePort.
