Kotlin LocalBroadcastManager not working after call to display values on UI

I have an android application I am working on in which I am making API request with Volley, after making the API call, I get a bunch of JSON objects returned. I now saved the values into a default values. after saving, I now tried displaying the values into my ui elements but everything is blank and does noy show the values. My codes are highlighted below

fun loginUser(context: Context, email: String, password: String, completion: (Boolean) -> Unit): Unit {

        val jsonBody = JSONObject()
        jsonBody.put("email", email)
        jsonBody.put("password", password)
        val requestBody = jsonBody.toString()

        val loginRequest = object : JsonObjectRequest(Method.POST, URL_LOGIN, null, Response.Listener {response ->

            try {
                userEmail = response.getString("user")
                authToken = response.getString("token")
                isLoggedIn = true
                completion(true)
            } catch (e: JSONException) {
                Log.d("JSON", "EXC:" + e.localizedMessage)
                completion(false)
            }
        }, Response.ErrorListener { error ->
            Log.d("ERROR", "Could not login user: $error")
            completion(false)

        }) {
            override fun getBodyContentType(): String {
                return "application/json; charset=utf-8"
            }
            override fun getBody(): ByteArray {
                return requestBody.toByteArray()
            }
        }
        Volley.newRequestQueue(context).add(loginRequest)
    }

fun findUserByEmail(context: Context, completion: (Boolean) -> Unit): Unit {
        val finUserByEmailRequest = object : JsonObjectRequest(Method.GET, "$URL_GET_USER$userEmail", null, Response.Listener {response ->
            try {
                UserDataService.name = response.getString("name")
                UserDataService.email = response.getString("email")
                UserDataService.avatarName = response.getString("avatarName")
                UserDataService.avatarColor = response.getString("avatarColor")
                UserDataService.id = response.getString("_id")
                val userDataChanaged = Intent(BROADCAST_USER_DATA_CHANGED)
                LocalBroadcastManager.getInstance(context).sendBroadcast(userDataChanaged)
                completion(true)
            } catch (e: JSONException) {
                Log.d("JSON", "EXC:" + e.localizedMessage)
                completion(false)
            }
        }, Response.ErrorListener { error ->
            Log.d("ERROR", "Could not find user: $error")
            completion(false)

        }) {
            override fun getBodyContentType(): String {
                return "application/json; charset=utf-8"
            }
            override fun getHeaders(): MutableMap<String, String> {
                val headers = HashMap<String, String>()
                headers["Authorization"] = "Bearer $authToken"
                return headers
            }
        }
        Volley.newRequestQueue(context).add(finUserByEmailRequest)
    }

my MainActivity

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        setSupportActionBar(toolbar)
        val toggle = ActionBarDrawerToggle(
                this, drawer_layout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close)
        drawer_layout.addDrawerListener(toggle)
        toggle.syncState()
   LocalBroadcastManager.getInstance(this).registerReceiver(userDataChangeReceiver, IntentFilter(BROADCAST_USER_DATA_CHANGED))
    }

    private val userDataChangeReceiver = object : BroadcastReceiver() {
        override fun onReceive(contect: Context?, intent: Intent?) {
            if (AuthService.isLoggedIn) {
                userNameNavHeader.text = UserDataService.name
                userEmailNavHeader.text = UserDataService.email

                val resourceId = resources.getIdentifier(UserDataService.avatarName, "drawable", packageName)
                userImageNavHeader.setImageResource(resourceId)
                userImageNavHeader.setBackgroundColor(UserDataService.returnAvatarColor(UserDataService.avatarColor))
                loginBtnNavHeader.text = "Logout"
            }
        }
    }
