I’m tryin to test the large-audio-room with the quickstart-calls-reactjs app provided. First, I have created the LARGE\_ROOM\_FOR\_AUDIO\_ONLY from SB dashboard. And then fetch and enter using the room id. I have checked the number of participants and participant id in the room information and it looked it was all working good. ![image](https://us1.discourse-cdn.com/flex020/uploads/sendbird/original/2X/5/55bc83376fa0e4d5988ea3af95b4412a069122f3.png) However, the microphone and audio did not seem to work. I followed the guide in the docs but still failed to play the audio. The setAudioForLargeRoom() fails with errors: ```auto SendBirdCall.min.js:6 Uncaught (in promise) Error: The participant is not in the room and the request can't be processed. at i.value (SendBirdCall.min.js:6:1) at i. (SendBirdCall.min.js:6:1) at tryCatch (runtime.js:63:1) at Generator.invoke [as _invoke] (runtime.js:294:1) at Generator.next (runtime.js:119:1) at xn (SendBirdCall.min.js:6:1) at i (SendBirdCall.min.js:6:1) at SendBirdCall.min.js:6:1 at new Promise () at i. (SendBirdCall.min.js:6:1) ``` It fails even if there is already a participant. Here are some code snippets for clearance. In index.html, added audio element after root: ```auto
``` In provider.tsx: ```auto const fetchRoomById = useCallback( async (roomId) => { const room = await SendbirdCall.fetchRoomById(roomId); if (room.roomType === SendbirdCall.RoomType.LARGE_ROOM_FOR_AUDIO_ONLY) { const audioElement = document.getElementById( "sb_audio" ) as HTMLAudioElement; room.setAudioForLargeRoom(audioElement); } ... ``` Please help to resolve the above error and enable microphone and audio. ---
