我正在努力處理這段程式碼，由於某種原因retrieveTutorials()它沒有將訊息傳遞給baseDeDatosVias。我嘗試將該功能更改為另一個生命週期，但不起作用。也許解決方案真的很簡單，但我找不到它。先感謝您的幫忙！ ！
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);
（我知道還必須修正所有“else if”）
完整程式碼如下：

看起來像是非同步問題 - 嘗試：
async populateGrados() {
await this.retrieveTutorials();
// rest of the code
}
