Firebase reading returns null

In my app I'm trying to get user information from Firebase database, but it always returns null. Here is my code for reading current user information from database

func workWithDataBase(){
let email = ""
let password = "test23"

FIRAuth.auth()?.signIn(withEmail: email, password: password, completion: { (user, error) in
if error != nil {
} else {
print("SIGNED IN\n")

let uid = FIRAuth.auth()?.currentUser?.uid

FIRDatabase.database().reference().child("users").child(uid!).observeSingleEvent(of: .value, with: { (snapshot) in
}) {
(error) in

and here is the output and the screenshot of Firebase database

My question is if the fields for email and name are not empty why "observeSingleEvent" method returns null? How can I fix this?

Try This:-

 FIRDatabase.database().reference().child("user").child(FIRAuth.auth()!.currentUser!.uid).observeSingleEvent(of: .value, with: { (snapshot) in
        }) {(error) in
