Problems with onInit in 1v79

Hi
I'm running a Pico on 1v80 and I was wondering if this problem still exists.

I have the following code:

var ssid, password, url, timeout, apiString, ledInterval, wifiReady, http, wifi, testUrl;

//network & http stuff
ssid = "myssid";
password = "mypassword";
url = "http://www.myserver.com";
wifiReady = false;

//timestuff
timeout = 60*1000;

//setup
apiString = "";

function clearLed() {
    //clear RGB Pixel
}

function handleData(data) {
    //dosomething
}

function getForecast() {
    if (wifiReady) {
        http.get(url, function (res) {
            apiString = "";
            res.on('data', function (data) {
                apiString += data;
                console.log(data);
            });
            res.on('close', function () {
                handleData(apiString);
            });
        });
    }
}

function onInit() {
  
    http = require('http');

    digitalWrite(B9,1); // enable on Pico Shim V2

    //init serial for Wifi
    Serial2.setup(115200, {rx: A3, tx: A2});

    //init LED bus
    SPI2.setup({baud: 3200000, mosi: B15});
    SPI2.send4bit([0, 0, 0], 0b0001, 0b0011);

    wifi = require("ESP8266WiFi_0v25").connect(Seri­al2, function (err) {
        if (err) {
            clearLed();
        }
        console.log("Connecting to WiFi");
        wifi.connect(ssid, password, function (err) {
            if (err) {
                clearLed();
                throw err;
            }
            console.log("Connected");

            //add a delay just to make sure an IP address was obtained
            setTimeout(function () {
                wifi.getIP(function (err, ip) {
                    if (err) {
                        clearLed();
                        throw err;
                    }
                    //console.log(ip);
                    wifiReady = true;
                    getForecast();
                });
            }, 2000);
        });
    });
    
    setInterval(getForecast, timeout);

}

When I upload the code to the Pico via the IDE and type save() the code works as expected as long as the Pico is connected to the laptop. However, when I use a USB power supply to power the Pico the code does not work (I don't see any requests from the Pico on the server). So I wonder whether I got something wrong with the save() method or whether the problem still exists. Thanks!
