I try to display customer profile on my apps, but these line of code makes app crash when I click on the profile button(profile page)

the error said that Attempt to invoke virtual method 'void android.widget.EditText.setText(java.lang.CharSequence)' on a null object reference

my name and address can be displayed but not my email and my phone number which is weird why it happen like that? 

I check my database it contains data, I got stuck here on how to solve my problems because the code can't read my email and phone number but can ready my name and address.

```
public class CustProfileActivity extends AppCompatActivity {

    TextView email;
    EditText name, address, phone;
    Button update;

    DatabaseReference databaseReference;
    FirebaseAuth firebaseAuth;
    String userId;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_cust_profile2);

        name = findViewById(R.id.name);
        address = findViewById(R.id.address);
        update = findViewById(R.id.update);

        databaseReference = FirebaseDatabase.getInstance().getReference("Customer").child("");
        firebaseAuth = FirebaseAuth.getInstance();
        userId = firebaseAuth.getUid();

        databaseReference.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                Customer cust = dataSnapshot.child(userId).getValue(Customer.class);

                name.setText(cust.name);
                address.setText(cust.home_address);
                phone.setText(cust.telephone_number);
                email.setText(cust.email);

            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {

            }
        });

```
