The error given by the Money Server is:
Money # 04:57:46 - [MONEY RPC]: handleCancelTransfer: Exception occurred when
transaction 94786877-9ed6-4d36-98d7-9a88f7b52acf:
System.NullReferenceException: Object reference not set to an instance of an
object
at OpenSim.Grid.MoneyServer.MoneyXmlRpcModule.handleCancelTransfer
(Nwc.XmlRpc.XmlRpcRequest request, System.Net.IPEndPoint remoteClient)
[0x00000] in <filename unknown>:0
This is because it’s attempting to dereference a string (if I do
UUID.Random().ToString()) or an empty value.
