ERR_MISSING_MESSAGE_PORT_IN_TRANSFER_LIST


需要在 transferList 参数中显式列出的对象在传给 postMessage() 调用的对象中,但未在 transferList 中为该调用提供。 通常,这是 MessagePort

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.
