Create reader will stuck on somewhere

The test code:

// client, err := pulsar.NewClient(getClientOptions())
// if err != nil {
// t.Fatal(err)
// }
// assert.Nil(t, err)
// defer client.Close()
//
// topic := newTopicName()
// ctx := context.Background()
//
// // create reader
// reader, err := client.CreateReader(pulsar.ReaderOptions{
// Topic: topic,
// StartMessageID: pulsar.EarliestMessageID(),
// })
// if err != nil {
// t.Fatal(err)
// }

Start by reproducing the shown Go client setup and the client.CreateReader call with EarliestMessageID. Identify where reader creation stops making progress and inspect the relevant client or reader entry point. Done means the reported reader creation no longer gets stuck and the behavior is covered by a regression test.
