Kotlin error : java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

Question

I'm using Kotlin with Android Studio 4.2.2

I have a form that releases informations to Firebase for a map application. It worked well but, it's been some days now that I have an error. When the user click on the button to confirm the form, the app crash and the next error appear :

The data is not sended to fire base. Also, the app is no longer able to retrieve other data from Firebase in the other activity.

the error is from this line ->

val addresses = gc.getFromLocationName(ville, 2)

Here is the code :

    class ValiderFormulaireMission : AppCompatActivity() {
    
        private lateinit var profilId : String
        private lateinit var firebaseUser: FirebaseUser
        private var storagePostPicRef : StorageReference? = null
    
        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
            setContentView(R.layout.activity_valider_formulaire_mission)
            storagePostPicRef = FirebaseStorage.getInstance().reference.child("Post Picture")
    
            firebaseUser = FirebaseAuth.getInstance().currentUser!!
            val pref = this.getSharedPreferences("PREFS", Context.MODE_PRIVATE)
            if (pref != null)
            {
                this.profilId = pref.getString("profilId", "none")!!
            }
    
            userInfo()
            btnValider.setOnClickListener {
    
                if (
                    formCodePostal.text.toString() == "") {
                    textErreur.visibility = View.VISIBLE
                    textErreur.text = "Oups.. Indiquez une adresse valide !"
                }
                else {
                    textErreur.visibility = View.GONE
                    val ville: String = formCodePostal.text.toString()
                    val gc = Geocoder(this, Locale.getDefault())
// ERROR IS HERE -> val addresses = gc.getFromLocationName(ville, 2)   
                    val address = addresses.get(0) 
    
                    val usersRef = FirebaseDatabase.getInstance().reference.child("Mission")
                    val postId = usersRef.push().key
                    val postMap = HashMap<String, Any>()
                    postMap["postid"] = postId!!
                    postMap["nommission"] = nomMission.text.toString().toLowerCase()
                    postMap["prixmission"] = textPrix.text.toString().toLowerCase()
                    postMap["firstname"] = nomUtilisateur.text.toString().toLowerCase()

                    // Récupère directement le user depuis firebase
                    postMap["publisher"] = FirebaseAuth.getInstance().currentUser!!.uid
                    usersRef.child(postId).updateChildren(postMap)
                    Toast.makeText(this, "La mission a été créé.", Toast.LENGTH_LONG)

                    if (p0.exists()) {

            )
        }
    
    
        override fun onStop() {
            super.onStop()
            val pref = this.getSharedPreferences("PREFS", Context.MODE_PRIVATE)?.edit()
            pref?.putString("profilId", firebaseUser.uid)
            pref?.apply()
        }
