I've noticed there's a pr #4104 fix this, but it seems not the solution

[HomyeeKing]

one solution is that the plugin author calling the listening event by hand
e.g.

configureServer(server){
    console.log(`configureServerSync`, server.config.server.port)
     
    server.httpServer?.once('listening',()=>{
   
        console.log('configureServer listening',server.config.server.port);
        
     })
}

Closing as it is impossible to implement it to those hooks and can be obtained after listening event.
