Hi
I’m trying to display my api in the wix code dropdown.
in the terminal, the backend is returning an array in table form with the values ​​of the api.
In the PAGE CODE is not showing in the dropdown button a forEach error appears. “Cannot read property ‘forEach’ of undefined”

import { lerLista } from 'backend/manualAPI_vs2'; 

// /*FRONTEND */
$w.onReady(() => {
    listarEquipamentos()
})

function listarEquipamentos() {
 let opcoes = []
 let listaDeEquipamentos = []

    lerLista("equipamentos")
 .then(async (lista) => {
            console. log(lista)

 await lista. Equipamentos.forEach((value, i) => {
                listaDeEquipamentos. push(value. nome_equipamento + "***" + value. id)
 })
            listaDeEquipamentos. sort(function (a, b) {
 return a. localeCompare(b);
 });
 await listaDeEquipamentos. forEach((pais, index) => {
 let dados = pais. split("***")
                opcoes. push({ "value": String(dados[1]), "label": dados[0] })
 })
            $w("#dropdown1"). options = opcoes
            $w("#dropdown1"). enable()
 })
}

backend
/*BACKEND */
import { fetch } from 'wix-fetch';
 
let ret
export async function lerLista(equipamentos) {
 const headers = {
 "Content-Type": "application/x-www-form-urlencoded"
 };
 const request = {
 "method": "get",
 "headers": headers,
 };
 
 const url = 'http://3b88a1d8ac67. ngrok. io/equipamentos';
    console.log("Url: " + url + '/?format=json');
 let fullUrl = url + '/?format=json'; 
 
 try {
 let httpResponse = await fetch(fullUrl, request)
 if (httpResponse. ok) {
            ret = await httpResponse. json()
 } 
 } catch (erro) {
        ret = await erro
 }
 return ret
}

It looks like lista is not an object with a property key Equipamentos .
Isn’t lista an array?

Few side notes:
front end - you don’t need the async and await (.forEach() is not a promise).
backend - the ret deceleration should be inside the function scope, not on the global scope. + No need to use await erro

3

this list is an array.
List is to show the names of “equipment”.
do you know any other simpler properties in wix code?

4

If it’s an array you can’t use lista.Equipamentos (arrays only have some built-in properties such as .length).

5

This “Equipmentos” is my table where we have a list of equipment.
I put it there to get the list from this table
http://3b88a1d8ac67. ngrok. io/equipamentos
