WitnessRules scope transactions can not be parsed #772
Description
Describe the bug
When a block has a transaction with a scope of WitnessRules, trying to parse it breaks with a null ref.
To Reproduce
this tx https://dora.coz.io/transaction/neo3/mainnet/0x91573ee0f131b98b16fd7f9e1b99756ca0c7c544f5ed687e86432168ea212437 in this block https://dora.coz.io/block/neo3/mainnet/2368604 is using WitnessRules as an example.
var client = new RpcClient(new Uri("http://seed1.neo.org:10332"), null, null, ProtocolSettings.Load("config.json"));
var block = await client.GetBlockAsync("2368604");
foreach (var tx in block.Block.Transactions)
{
Console.WriteLine(tx.Hash.ToString());
}
exception thrown:
Unhandled exception. System.NullReferenceException: Object reference not set to an instance of an object.
