Fetch keys from external source

[wardamn]

Is it possible to fetch my keys from an API endpoint that returns an array? Something about the promise is giving me the following TypeError for trying to iterate over it.

autoComplete.js:119 Uncaught (in promise) TypeError: Invalid attempt to iterate non-iterable instance. In order to be iterable, non-array objects must have a Symbol.iterator method.

data: { src: async () => { try { // Loading placeholder text document.getElementById("autoComplete").setAttribute("placeholder", "Loading..."); // Fetch External Data Source const source = await fetch("/suppliers"); const data = await source.json(); console.log(data) // Post Loading placeholder text document.getElementById("autoComplete").setAttribute("placeholder", autoCompleteJS.placeHolder); // Returns Fetched data return data; } catch (error) { return error; } }, keys: fetch("/keys").then(response => response.json()) //.then(jsonData => console.log(jsonData) ), cache:true

Please share a sample of the return from "/suppliers" and "/keys."
