I get an stream.getTracks is not a function error in PeerJS. How do i fix this?

Question

so I have been using PeerJS to make a p2p chat application and it works when trying to chat, but when i try to call someone with the function below:

function callEm(id){
  call = peer.call(id,
    navigator.mediaDevices.getUserMedia({video: false, audio: true})
    );

  call.on('stream', function(stream) { // B
      window.remoteAudio.srcObject = stream; // C
      window.remoteAudio.autoplay = true; // D
      window.peerStream = stream; //E
      showConnectedContent(); //F    });
  })
  }

I get an error from PeerJS saying that e.getTracks is not a function e.getTracks is a code in the peerJS library: https://unpkg.com/peerjs@1.3.1/dist/peerjs.min.js

I have been trying everything i find on the internet and I still get this error. I hope someone will be able to help me out.

Edit: I tried the cleaner version of the library( https://unpkg.com/peerjs@1.3.1/dist/peerjs.js) and i get the error stream.getTracks() is not a function

Answer 1

So I found the solution, the thing is my code was wrong :P

so I created a function that calls a person with an Id. earlier it was:

function callEm(id){
  console.log(id);
  console.log(navigator.mediaDevices.getUserMedia({video: false, audio: true}));

  call = peer.call(id,
    // window.localStream
    navigator.mediaDevices.getUserMedia({video: false, audio: true})
    );

  call.on('stream', function(stream) { // B
      window.remoteAudio.srcObject = stream; // C
      window.remoteAudio.autoplay = true; // D
      window.peerStream = stream; //E
      showConnectedContent(); //F    });
  })
  }

and the issue was that I provided a promise as a MediaStream instead of the actual value. dumb mistake I know

so after a friend in discord pointed that to me and helped me change it, the function became:

function callEm(id){
  navigator.mediaDevices.getUserMedia({video: false, audio: true})
  .then(function(stream) {
        call = peer.call(id, stream);
        call.on('stream', function(stream) { // B
          window.remoteAudio.srcObject = stream; // C
          window.remoteAudio.autoplay = true; // D
          window.peerStream = stream; //E
          showConnectedContent(); //F    });
        })
    })
    .catch(function(err) {
      console.log("error: " + err);
    })
  );
  }

and that fixed it. I didn't work out on answering the call yet, but this sent a call without any errors!

I hope someone finds this useful.
