how to send audio stream between child processes in nodejs

How do i properly send stream to a child process. I am trying to stream audio from client to server using this method

I am getting the audio stream from client

const ss = require('socket.io-stream');
const socketIo = require('socket.io');

server = http.createServer(app);
io = socketIo(server);

const child_process = childProcess.fork('./child_process.js');


io.on('connect', (client) => {


    // when the client sends 'stream-transcribe' events
    // when using audio streaming
    ss(client).on('stream-transcribe', function(stream, data) {
     
    var combine_data = {
            "data": data,
            "stream": stream,
            "event":"new_stream"
          }
    
     child_process.send(combine_data)


  }


}
 

this call

     child_process.send(combine_data)

throws the error

node:internal/child_process/serialization:127 const string = JSONStringify(message) + '\n'; ^
