PhotonRealtime internal exception after upgrading PUN2 from 2.17 to 2.18

Lightbringer

Hi,
I just upgraded PUN2 in a Unity 2019.3.7f1 project from 2.17 to 2.18. The code works fine with the old version, but
raising an event like this:

byte eventCode;
int id;
MyEnum e;
object o; //o actually being a string with 95 characters
RaiseEventOptions options = new RaiseEventOptions
{
       CachingOption = EventCaching.AddToRoomCacheGlobal,
       Receivers = ReceiverGroup.Others
 };
SendOptions so = new SendOptions
{
      DeliveryMode = DeliveryMode.Reliable
};

PhotonNetwork.RaiseEvent(eventCode, new[] {id, e, o}, options, so);

now throws the following exception:

ArgumentOutOfRangeException: Index and count must refer to a location within the string.
