System.InvalidCastException in TicketCancelResponse.Acknowledge

[aaubry]

We are getting a System.InvalidCastException while using the SDK:

Unable to cast object of type 'Sportradar.MTS.SDK.Entities.Internal.TicketImpl.Ticket' to type 'Sportradar.MTS.SDK.Entities.Interfaces.ITicketCancel'

It happens at this location:

        public void Acknowledge(bool markAccepted = true)
        {
-           var sentTicket = (ITicketCancel)_ticketCancelSender.GetSentTicket(TicketId);
            if (sentTicket == null)
            {
                throw new InvalidOperationException("Missing ticket in cache");
            }
            Acknowledge(markAccepted, sentTicket.BookmakerId, Reason.Code, Reason.Message);
        }

This code assumes that the cast to ITicketCancel is legal, but in this case the method is returning an instance of Sportradar.MTS.SDK.Entities.Internal.TicketImpl.Ticket, which doesn't implement that interface.
