Frontend with previous methods used:
// Velo API Reference: https://www.wix.com/velo/reference/api-overview/introduction
$w.onReady(function () {
// Write your Javascript code here using the Velo framework API
// Print hello world:
// console.log("Hello world!");
// Call functions on page elements, e.g.:
// $w("#button1").label = "Click me!";
// Click "Run", or Preview your site, to execute your code
});

This is what I get in the console:
Sending data: {"lat":49.2526028832592,"lon":-123.00380973189016,"max_distance":1500,"stop_filter":"All","pickup_dropoff_filter":"Everything"}
{...}
stops: Array(0)
With Verbose enabled:
[datasetReady event] triggered on wix-dataset

{...}
stops: Array(0)
[wix-dataset.getTotalCount] called
[wix-dataset.getTotalCount] returned with ( 0 )
Using the coordinates on Google Maps, there are supposed to be bus stops within 1500 m. As you see what I got in the console, I got no results. I thought about simplifying the backend with using getJSON() in my revision since I am only getting data from the Transit app via HTTPS.
Just tried out an idea I currently have in mind which is emulating the example in the Wix dev doc article about getJSON():
import { getJSON } from "wix-fetch";
// ...
getJSON("https://someapi.com/api/someendpoint")
.then((json) => console.log(json.someKey))
.catch((err) => console.log(err));
