Getting Cannot read property 'appendChild' of null on switchDevice method call

[kush3107]

I am trying to switch the input device for the current local stream. I am on sdk version 3.0.2 but when I try to do so I get the error in the attached screenshot. I followed this link

This link clearly says that I just need to call this method above version 2.5.0
I have attached the console error

[kush3107]

switchDevice(type: 'audio' | 'video', deviceId: string): Promise<void> {
        console.log(type, deviceId);
        this._currentStream?.stop();
        
        return new Promise((resolve, reject) => {
            // @ts-ignore
            this._currentStream?.getAudioTrack().stop();
            this._currentStream!.switchDevice(type, deviceId, () => {
                resolve();
            }, reject);
        });
    }
