designParamTypeList in @ParamType is undefined?
@Hook(agentTarget('hookLogoutEventCallback'))
logoutEvent (
@ParamType('int32', 'U32') bySrv: number,
) { return Ret(bySrv) }
The @ParamType causes the following error:
D:\编程\github\wechat-hook\node_modules\sidecar\src\decorators\param-type\guard-param-type.ts:26
const designParamType = designParamTypeList[parameterIndex]
^

If I don't include @ParamType , the application works without any errors.
Would appreciate it if you can provide more information or a minimum code with reproducible steps.

Some of this code was taken from wechaty-xp, just experimenting with sidecar because this is my first time. Will later use this with a newer version of WeChat. I am currently using the latest version of "sidecar": "^1.0.19".
Thanks for the new information.
I will take a look when I got time with a windows VPS . (Currently I have no windows dev machine)
Have you joined the XP WeChat room? If not, please feel free to san the below qrcode to join and ask your question over there, with other sidecar users.
