5.3.0 docker

Run or Compiler Version

golang 1.23, 1.19

Describe the Bug

I was trying out go sdk for v5, i follow https://rocketmq.apache.org/docs/sdk/05go/ , but when i try to run the producer, it got nil pointer error at

err = producer.Start()

i can confirm that producer itself is not nil. Also in the consumer,

golang.WithSubscriptionExpressions(map[string]*golang.FilterExpression{
            Topic: golang.SUB_ALL,
        }),

this seem to be changed, it is now expression and expresssionType, rather than Topic.

Steps to Reproduce

follow https://rocketmq.apache.org/docs/sdk/05go/
