Telr WebView doesn't redirects me to Failed or Success Activity, Unable to Cast Status Response into Failed Status Reponse

Question

I am implementing Telr Payment Gateway in Android. I have been facing issues while my transaction is failed or even successful the Telr's WebView doesn't redirect me to the Failed or Success Activity. And if it fails I get a crash which tells that:

java.lang.ClassCastException: com.telr.mobile.sdk.entity.response.status.StatusResponse cannot be cast to com.telr.mobile.sdk.entity.response.status.StatusResponseFailed

Following is my Payment Fragment code which has a method named "sendMessage"(which opens WebView through intent) then there is a method named "messageRequest" which requests all the required data for a transaction WebView to be set:

    private lateinit var binding: FragmentPaymentBinding
    val isSecurityEnabled = true
    val REQUEST_CODE = 100


    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        val sharedPref: SharedPreferences =
            requireContext().getSharedPreferences("telr", Context.MODE_PRIVATE)

        val ref = sharedPref.getString("ref", null)
        if (ref != null) {
            binding.btnSavedCards.visibility = View.VISIBLE
        } else {
            binding.btnSavedCards.visibility = View.GONE
        }
        binding.btnPay.setOnClickListener {
            sendMessage()
        }
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)
        if (requestCode == REQUEST_CODE &&
            resultCode == Activity.RESULT_OK
        ) {
            val paymentMethod: String = data?.getStringExtra("auth").toString()
            if (paymentMethod.equals("yes", ignoreCase = true)) {
                val status =
                    data?.getParcelableExtra<Parcelable>(WebviewActivity.PAYMENT_RESPONSE) as MobileResponse

I have been looking for solutions but am unable to do so. Any sort of help would be highly appreciated.
