when use send method occur error

[modifyFun]

I use like this
`export const sendCommand = async (port, baudRate, command) => {
const serialPort = await serialPortApi.open(port, { baudRate });

await serialPort.send(command);

serialPort.close();
};
sendCommand('/dev/ttyS2', 9600, '57AA08CC33C33C');`

an ”exception in native call from js error“ was occur，the command is send and work , but app occur error
