How do I set metadata in the PeerJs peer.call(id, stream, [options]) function?

I am trying to send two calls in a peer connection and I want to differentiate them through meta_data but I get null when I check meta_data. How can I add meta_data on making calls? This my current code.

let cameracall = peer.call(conn.peer,ourcamera,{
    meta_data:JSON.stringify({ "type":"camera" })
});
let screencall = peer.call(conn.peer,ourscreen,{
meta_data:JSON.stringify({"type":"help"})
});

Here is a link to the documentation peercall

peer.on('call', call => {
    call.answer(localStream);

    call.on('stream', remoteStream => {
        console.log(call.metadata.type)
    });
});

peer.call(peerId, localStream,
    {
        metadata: {
            "type": "help"
        }
    }
);

You can get the metadata inside on call.

for calling a remote peer in normal way without metadata we have:

peer.call(remotePeerId, ourLocalStream);

for calling a remote peer + attaching some metadata to the call:

options = {metadata: {"type":"screensharing"}};
peer.call(remotePeerId, ourLocalStream, options);

on remote peer side, for checking metadata in received call:

 peer.on('call', call => {
    console.log(call.metadata.type);
    call.answer();
    call.on('stream', stream => {
       // somthing to do
    });
 });

please note for other calls that maybe does not have any metadata defined for them, call.metadata.type does not make any sense.

There is a syntax issue. You need to do this for sending metadata with a stream

let cameracall = peer.call(conn.peer, ourcamera, {
    metadata: { "type": "camera" }
});
let screencall = peer.call(conn.peer, ourscreen, {
    metadata: { "type": "help" }
});

And then at the peer end, you can get metadata like this

peer.on("call", connection => {
  connection.answer();
  connection.on("stream", stream => {
    console.log(connection.metadata);
  });
});
