Realtime database not getting data pushed into firebase

Question

I'm using realtime database to save user info but the problem is that it is not working at all , meanwhile storage and cloud firestore work properly , tried changing rules , tried different methods but none really worked , if someone could help thank you in advance .

• This is my code

class CustomerRegistrationActivity : AppCompatActivity() {
    private lateinit var imageDownloadUrl : String
    private var imageUrl : Uri? = null
    private lateinit var firebaseAuth: FirebaseAuth
    private lateinit var databaseReference: DatabaseReference
    private lateinit var storageReference: StorageReference
    private var _binding : ActivityCustomerRegistrationBinding?  = null
    private val binding get() = _binding!!
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        _binding = ActivityCustomerRegistrationBinding.inflate(layoutInflater)
        setContentView(binding.root)


        init()

        binding.register.setOnClickListener {
            binding.register.startAnimation()
            registerNewCustomer()
        }

        binding.customerImg.setOnClickListener {
            selectCustomerImage()
        }

        binding.haveAccount.setOnClickListener {
            Intent(this, CustomerLoginAcitivity::class.java).apply {
                startActivity(this)

• Realtime db rules

{
  "rules": {
       ".read": "auth !== null",
       ".write": "auth !== null"
  }
}

Answer 1

Try to remove .await() while pushing and set db rules to true

".read": true,
".write": true
