Remove User From Access Team

Hi, I've a plugin which used to be worked for CRM 2013 before update to roll up 1.

RemoveUserFromRecordTeamRequest adduser = new RemoveUserFromRecordTeamRequest()
            {
                Record = record,
                SystemUserId = systemuserId,
                TeamTemplateId = teamTemplateId
            };

But not I received the following messages.

Access team for team template for record of type {1} and id {0} and not found.

Do I need to check if the user already added to the team before deleting it?

thanks
