Impossible to pass JSON parameters with back button

i can’t add JSON parameters to my back button with this code :

constructor(private navCtrl: NavController,private platform: Platform,private route: ActivatedRoute, public formBuilder: FormBuilder,private myStorage: StorageService,private router: Router, private userService: UserCrudService, private dataService: DataService, private authService: AuthService) {
this.formPresence= this.formBuilder.group({
presM: false,
presA: false,
typeAbsence: null // Ajout du nouveau contrôle de formulaire
});
console.log(this.formPresence.value);
// this.token=localStorage.getItem('token');
//let decoded = jwt_decode(this.token);
//console.log(decoded);
try {
  this.backButtonSubscription =this.platform.backButton.subscribeWithPriority(5, () => {
  console.log(this.parameters);
    const param=JSON.stringify(this.parameters);
    console.log(param);
    this.router.navigate(['/accueil', {param}])
  });
}
catch (error :any){
  console.log(error.toString());
}

        }
        console.log(this.parameters);
         try{
