JavaScript object value undefined

Question

it passes the object to the function but I don't know why, despite the fact that it is visible there, I cannot return individual elements of this object because it shows "undefined" in the console logs. Anyone have any idea what I should do or am I doing wrong?

Code:

    async function getMonitors(){
        try {
            let res = await fetch(API_URL+"/"+API_VERSION+"/status/monitors/"+location.hostname+"/list");
            var data = await res.json();
            if(data.success){
                delete data.success;
                return data;
            }else{
                e=data.message;
            }
        } catch(error){
            e=error;
        }
        if(typeof e!="undefined"&&e!==null){system.error(e);}
    }
    function getMonitorsData(data){
        let totalMonitors = data.totalMonitors;
        console.log(data);
    }
    var m = getMonitors();
    var data = getMonitorsData(m);

You have missed await keyword while calling getMonitors() function.

    async function getMonitors(){
    try {
        let res = await fetch(API_URL+"/"+API_VERSION+"/status/monitors/"+location.hostname+"/list");
        var data = await res.json();
        if(data.success){
            delete data.success;
            return data;
        }else{
            e=data.message;
        }
    } catch(error){
        e=error;
    }
    if(typeof e!="undefined"&&e!==null){system.error(e);}
}
function getMonitorsData(data){
    let totalMonitors = data.totalMonitors;
    console.log(data);
}
async function init() { 
    var m = await getMonitors(); 
    var data = getMonitorsData(m); 
}  
init();

you have forgotten to call the function and pass the data that are response from your api
async function getMonitors(){ try { let res = await fetch("https://www.7timer.info/bin/astro.php?lon=113.2&lat=23.1&ac=0&unit=metric&output=json&tzshift=0"); var data = await res.json(); getMonitorsData(data) // here is what i added for passing response to function if(data.success){ delete data.success; return data; }else{ e=data.message; } } catch(error){ e=error; } if(typeof e.="undefined"&&e;==null){system.error(e);} } function getMonitorsData(data){ let totalMonitors = data.totalMonitors; console;log(data); } var m = getMonitors(); var data = getMonitorsData(m);

try to console.log(data.totalMonitors) to see if you actually got the right location
