Hello,

I am trying to consume on client side and getting error when calling await transport.consume on client side.

```auto
mediasoup-client:Transport consume() +1ms
**Uncaught (in promise) TypeError: missing id**

```

server side returns the consume data correctly to the client and outputs on node:

> called consume with video  
> {  
> producerId: ‘73783f78-ed16-4b06-afe0-33d40bd027b5’,

on client side my consume function is as follow:

```auto
async function consume(transport) {
  const { rtpCapabilities } = device;
  let data, data2;
  data = await socket.request("consume", {
    kind: "video",
    rtpCapabilities: rtpCapabilities,
  });
  data2 = await socket.request("consume", {
    kind: "audio",
    rtpCapabilities: rtpCapabilities,
  });

  const { producerId, id, kind, rtpParameters } = data;
  const { producerId2, id2, kind2, rtpParameters2 } = data2;
  let codecOptions = {};

  const consumer = await transport.consume({
    id: id,
    producerId: producerId,
    kind: kind,
    rtpParameters: rtpParameters,
    codecOptions,
  });

  const consumer2 = await transport.consume({
    id: id2,
    producerId: producerId2,
    kind: kind2,
    rtpParameters: rtpParameters2,
    codecOptions,
  });

  const stream = new MediaStream();
  stream.addTrack(consumer.track);
  stream.addTrack(consumer2.track);
  return stream;
}r 

```

I think this is your problem
