I am trying to share a file over WebRTC but after some time it stops, and log RTCDatachannel send queue is full

Question

let file = fileUpload.files[0];
let offset = 0;
let chunkSize = 1024*1024*16;


file.arrayBuffer().then((buffer) => {
            
 while(buffer.byteLength){
                
       const chunk = buffer.slice(0, chunkSize);
       buffer = buffer.slice(chunkSize, buffer.byteLength);
      dataChannel.send(chunk);
  }
})

it works fine for small files but stops with big size files.
