**Description**  
I have errors when using the getBreakoutRoomList function.  
When I try to get the breakoutroom list and all attendees, i’m getting en error 3003, I saw that this error was related to the fact that only the host can call this function but when i’m using getCurrentUser, isHost is true.  
Half of the time I have a js error with this function. (every time I want to use a timeout or an interval to delay the result)

**Browser Console Error**  
error when using timeout and the function : ERROR TypeError: Cannot add property attendees, object is not extensible  
error when using the function : error 3003

**Which Web Meeting SDK version?**  
2.1.1

```auto
        ZoomMtg.init({
            leaveUrl: environment.frontendUrl + this.redirectUrl,
            success: () => {
                ZoomMtg.join({
                    signature,
                    apiKey,

                    tk: '',
                    // eslint-disable-next-line
                    success: () => {
                        console.log('joinmeeting success')
                    },
                    error: (error: any) => {
                        console.log(error);
                    },
                });
                setTimeout(() => {
                    // always fail: error 3003 or js error
                    // in this case js error cause of the timeout
                    ZoomMtg.getBreakoutRoomList({
                        success: (success: any) => {
                            console.log("getBreakoutRoomList", success)
                        },
                        error: (error: any) => {
                            console.log(error)
                        }
                    });
                    // success
                    ZoomMtg.getCurrentUser({
                        success: (success: any) => {
                            console.log('currentuser', success);
                        }
                    });
                    // success
                    ZoomMtg.getAttendeeslist({
                        success: (success: any) => {
                            console.log('currentAttendees', success);
                        }
                    });
                }, 10000)
            },
            error: (error: any) => {
                console.log(error);
            },
        });

```

**Device (please complete the following information):**

- Browser: Chrome

**Additional context**  
The function is always called inside the success callback of the init function. I tried putting this function inside and outside the join function. I want to get the breakout room list of attendees every 10ish second.
