update single document field in firestore

I have a document ref user/userid23435534 and I want to update a single (document has several fields) field(nick) in that document.

I call this method: ref.ref.update("nick","test123") and I can see from logging that ref.getpath() is user/userid23435534 indeed.

However, after calling this method, and getting success from my OnSuccessListener I still see that my field is not updated in the firestore database. What did I get wrong here?

EDIT:

public static void updateDocument(){
    final DocumentReference ref = db.collection("user").document("userid23435534");
    ref.update("nick", "test123" )    //logging shows that red.getPath is "user/userid23435534"
        .addOnSuccessListener(aVoid -> {
            //success is called when calling method that runs this code
        }).addOnFailureListener(e -> {
            //....
        })
 }

I just ran this code in my local emulator, and it updates the document without problems:

DocumentReference ref = db.collection("56246892").document("uid");
ref.update("nick", "test123" ).addOnSuccessListener(new OnSuccessListener<Void>() {
    @Override
    public void onSuccess(Void aVoid) {
        System.out.println("Updated");
    }
});

Are you sure the document already exists? That is required for update() to work. If you're not sure whether the document exists, use set(..., SetOptions.merge()).
