连接SIMNO CTP，rpc client连接RPC gateway时会报这个错。但看起来客户端能订阅到行情信息

RPC接口似乎用得人并不多吗？社区目前是不是没有改成纯WEB页面的计划呀

vnpy和vnpy_rpcservice都是最新版本的吗？

In [471]: vnpy.__version__
Out[471]: '3.9.3'

In [472]: vnpy_rpcservice.__version__
Out[472]: '1.1.0'

可以都升级到最新版本之后再试

升级了，还是有问题

另外，RPC client 能接收到来自 server 的资金信息，但没有持仓信息

现在vnpy和vnpy_rpcservice的版本分别是？
具体什么操作复现这个报错呢？

前面两个exception看起来原因是client和server的语言不一致导致的，我目前server是中文，client是英文。如果猜测没错的话，这个也不太算BUG吧，我自己还能解决。

Out[32]: '4.2.0'

In [33]: vnpy_rpcservice.__version__
Out[33]: '1.1.0'

请问 @xiaohe 大佬，RPC网关会同步持仓和交易信息吗？我目前来看是没有同步到。不确定跟前述语言不一致的问题是否有关联。
