Fetch Web API data from companion in the simulator

[santiagortiiz]

Hi, I am trying to set up the communication between the companion and any Web API using the Fetch function using the Fitbit Studio Simulator.

Fitbit Studio Details:
Device: Versa 3
SDK version: 5.0

Permissions: Internet & Run in background

Companion code:

import * as messaging from "messaging"
import { me as companion } from "companion"

const myHeaders = new Headers({'Content-Type': 'application/json'})
const API = 'https://rickandmortyapi.com/api/character/1'

console.log("BEFORE")
fetch(API, {
    method : "GET",
    headers : myHeaders,
    // body: ''
}) 
    .then((response) => {
        console.log(response.json())
    })
    .then((data) => {
        console.log(data)
    })
    .catch ((err) => {
        console.error(err)
    })
console.log("AFTER")

* Console Result *

BEFORE

The 'permission' API is not yet supported in the Fitbit OS Simulator. Behavior may not match the documentation or real devices.

AFTER

{}

null

Does anybody know how I can fix it? Thanks in advance!

fetch() is promise based, so "AFTER" isn't really after the fetch occurs.

Looks like you solved this in another thread anyway.

Thanks Jon, the problem I report is that the fetch was empty, not the order of the logs, but I fixed it and shared it in that link you added.
