I have the following function:
async geraQuiz(idEstudante) {
let idioma = new Array()
let livrosUnidadesGerarQuiz = new Array()
const idsClassesEstudante = await this.getIdClassesEstudante(idEstudante) // Aqui obtenho como retorno o array [2,3]
for(let i=0;i<idsClassesEstudante.length;i++){
livrosUnidadesGerarQuiz = new Array() // Limpa o array para retirar objetos de iterações anteriores
idioma.push(await this.getDadosClasseIdiomaEstudante(idsClassesEstudante[i]))
livrosUnidadesGerarQuiz = await this.getLivrosUnidadesGerarQuiz(idsClassesEstudante[i], idBookClasseEstudante[0], qtdQuizGerar)
idioma[i].quiz = livrosUnidadesGerarQuiz
console.log(JSON.stringify(idioma))
console.log(idioma[i].quiz[0])
...
On the console.log idioma, i have the following object array:

But when I try to access: console.log(idioma[i].quiz[0]) i get undefined, but my console.log() clearly shows that there is a quiz property within the language at position 0, but I cannot access it because it is undefined. 'Cause this is happening?
I put a return shortly after the console.log(idioma[i].quiz[0]) to check if you are not overwriting something later, but get the same result; and
I put a console.log(i) and get 0 as expected.
Try changing language[i]. quiz[0] by language[0]. quiz[i]
– Benilson
Undefined, as the question, i has the value 0
– veroneseComS
By the.log console of the language you presented, there is only one object at zero position of the array and this object contains a list of objects in the quiz attribute.
– Benilson
yes, and when I try to access it I get Undefined
– veroneseComS
The problem is that obtaining this list is asynchronous
– bfavaretto
but await does not wait for the request to finish to continue the execution of the code?
