5 golang 实现ETH 交易离线签名(冷签)交易时出现错误

rlp: input string too short for common.Address, decoding into (types.Transaction)(types.txdata).Recipient

这个是我的:

[go-ethereum](https://github.com/ethereum/go-ethereum) version:1.8.20

rawTxHex:f86d808504a817c800825208944592d8f8d7b001e72cb26a73e4fa1806a51ac79d880de0b6b3a76400008081eda006d7f604cebd917db3b6bca27a2df342c837815bffa58bd86f11cdcee87f12c6a0787278c1a27d4a02608172019821323b271221382cd4597330c9c4bde5625ea5

http://gateway.moac.io/testnet是从以太坊fork的,但修改了交易结构(增加了几个字段),所以会出现这个错误。官方有提供golang的sdk。
