Problèmes de méthodes et de cycle de vie dans VueJS

Question

J'ai du mal avec ce code et pour une raison quelconque, retrieveTutorials() ne transmet pas les informations à baseDeDatosVias. J'ai essayé de changer la fonction vers un autre cycle de vie mais cela n'a pas fonctionné. La solution est peut-être très simple mais je ne la trouve pas. Merci d'avance pour votre aide! !

methods: {
  retrieveTutorials() {
    TutorialDataService.get(this.$auth.user.name)
      .then(response => {
        this.baseDeDatosVias = response.data;
        console.log(this.baseDeDatosVias);
      })
    .catch(e => {
      console.log(e);
    });
  },


  populateGrados() {
  this.retrieveTutorials();
  this.cantViasEncadadenasPorGrados= [];
  const keys = Object.keys(this.baseDeDatosVias);
  console.log(keys);

(Je sais que je dois aussi corriger tous les "sinon si")

Le code complet est le suivant :

Cela ressemble à un problème asynchrone - essayez :

async populateGrados() {
    await this.retrieveTutorials();
    // rest of the code
}
