call GetRawTransactions and then call DecodeRawTransactions

[guobingithub]

hello author， when I call GetRawTransactions and then call DecodeRawTransactions, I just got result is as follows：
{
"txid": "4362785b9a52cea3591341384f28df422f22e35ceb84108daf1d47f3de465b66",
"hash": "cb0a50bb3c71d15ccf58315b2fb1b81cee3c9bf812220c0d0481778eba884d72",
"id": 0,
"size": 405,
"vsize": 214,
"locktime": 0,
"Vins": null,
"Vouts": null
}

Why Vins and Vouts are null??? Actually they are not null, can you help me for this problem？

Thanks very match!
