No source file or test is named. Start by tracing the client initialization path associated with HeartbeatSenderInitFunc and compare it with the supplied logs, then identify why the sentinel-dashboard connection and heartbeat initialization are absent. Done means the cause is reproducible and the client connects and initializes heartbeats as expected.
