Problem Description‌
When using go-zero v1.8.3, the RPC service can successfully register with etcd. However, when using the go-zero client (which relies on etcd/client/[email protected]), the following behavior occurs:

Works normally with {"etcdserver":"3.5.21","etcdcluster":"3.5.0"}
Fails with {"etcdserver":"3.5.21","etcdcluster":"3.0.0"}, producing the error:
