Swift-Firebase multiple observers

In a view controller, I have multiple observer codes. All of them working correctly except one. I'm sure child paths are correct. Observe function is correct. I tried in different a view controller and it worked correctly. Here is my firebase structure: Firebase structure

And here is my observer function.

func downloadUserData(){
    if let currentUser = FIRAuth.auth()?.currentUser{
        print("AZAT: download user data id \(currentUser.uid))")
        DataService.ds.REF_USERS.child(currentUser.uid).observe(  .value, with: {(snapshot) in
        if let userDict = snapshot.value as? Dictionary<String,Any>{
            print("AZAT: userdict is \(userDict)")
            let user = User(userData: userDict)
            self.users.insert(user, at: 0)
        }
        })
    }
}

And I call this function in viewDidLoad(). The REF_USERS is correct, I'm pretty sure.

Thanks for your help.

    if let lastNameReceived = (snapshot.value as? NSDictionary)?["lastName"] as? String{
     print("lastName value is \(lastNameReceived)")
   }
     if let userDict = snapshot.value as? Dictionary<String,Any>{
        print("AZAT: userdict is \(userDict)")
         let user = User(userData: userDict)
           self.users.insert(user, at: 0)
