Change the webcam settings to "Allow" or "Ask". If you select "Ask" which is a default permission, you will be prompted to give permission everytime you join a meeting. If you select "Allow", the app won't prompt you, but will notify you that the webcam is on when joining the meeting.

Select "Allow" and thats it. You should no longer get the webcam "overconstrained error".

On firefox, it will appear as below. Click on "right faced chevron" next to "Connection secure".
