webRtc节点js中的问题

Question

每当我运行此代码时，我都会收到存在房间的错误：false， 在firebase数据库中创建了room，但是，当我在服务器上运行它时，仍然在控制台上看到一个错误，指出房间存在：false

 function joinRoom() {
  document.querySelector('#createBtn').disabled = true;
  document.querySelector('#joinBtn').disabled = true;

  document.querySelector('#confirmJoinBtn').
      addEventListener('click', async () => {
        roomId = document.querySelector('#room-id').value;
        console.log('Join room: ', roomId);
        document.querySelector(
            '#currentRoom').innerText = `Current room is ${roomId} - You are the callee!`;
        await joinRoomById(roomId);
      }, {once: true});
  roomDialog.open();
}

async function joinRoomById(roomId) {

  const db = firebase.firestore();
  const roomRef = db.collection('rooms').doc(`${roomId}`);
  const roomSnapshot = await roomRef.get();
  console.log('Got room:', roomSnapshot);
  console.log('Got room:', roomSnapshot.exists);


  if (roomSnapshot.exists) {
    console.log('Create PeerConnection with configuration: ', configuration);
    peerConnection = new RTCPeerConnection(configuration);
    registerPeerConnectionListeners();
    localStream.getTracks().forEach(track => {
      peerConnection.addTrack(track, localStream);
    });


}
