关于合约事件监听的问题

我是copy代码库中的example下的event示例代码，但是也是监听不到，

是不是和我的bcos版本有关系，bcos是2.8的版本，go-sdk是dev版本，

Start with the event example in the repository and reproduce the report using BCOS 2.8 with the dev version of go-sdk. Check the SDK's documented version compatibility and the example's event-listening setup; done means identifying whether the version combination is supported and documenting or isolating the cause of the missing events.
