Buttons disabled about firebasertc

I also came across this error.

First started with : https://webrtc.org/getting-started/firebase-rtc-codelab . It also have similar error. So switched to solution branch and tried.

The screenshot below is using solution branch.

Looking into the console there is some more information.

Note : Camera, Microphone etc is already attached. Tested on Firefox ( 81.0.2 (64-bit) ) and Chrome ( Version 85.0.4183.121 (Official Build) (64-bit) )

@harikt @MajesticKhan It's not clear from the actual tutorial, but you have to click the "Open camera and microphone" button before it enables the create/join room buttons. This is how the code is designed as well. If you look at index.html, you'll notice the create/join rooms start out as disabled. In app.js, the init method adds a click eventListener on all the buttons, notably the #cameraButton to call openUserMedia(...) when someone clicks the open camera button. Within openUserMedia it gets camera/mic feed, and then:

document.querySelector('#cameraBtn').disabled = true;
  document.querySelector('#joinBtn').disabled = false;
  document.querySelector('#createBtn').disabled = false;
  document.querySelector('#hangupBtn').disabled = false;

to enable the other buttons.

I think it's working as intended.
