If you come across the problem that you will see an error 500 when scheduling a SurveyVideo. It means that there is some information missing that the system needs in order to schedule the video. 

 

When this occurs, it is important to check if the city and the country are filled in. The reason for this is because, the system needs to display a time zone. Without the time zone the error 500 will occur, which will lead to your client not receiving a confirmation email.
