Survey 123: Need help modifying a javascript to get X value from json file based on lat long of geopoint

I am trying to get a script together that would based on a geo point lat long return the label of a line segment by proximity. This could also be the devices own lat long as soon as the survey opens if easier. Here is some code work that Ismael from Esri had done and I tried modifying it. However, my java is terrible. The below code block pulls the nearest record when I want to pull the nearest value of the field Label. it also has it point to a web service when I want it point to the json stored within the media folder media/scat_segment.json. Any help would be appreciated

function getNearestRecord(featureLayer, location, searchWithinMeters,fields,where,token,debugmode){
    
    if (featureLayer==="" || featureLayer===undefined){
        featureLayer = "https://services.arcgis.com/P3ePLMYs2RVChkJx/ArcGIS/rest/services/USA_Major_Cities/FeatureServer/0";
    }

    if (location==="" || location===undefined){
        return (debugmode? "Location Object is empty":"");
    }

    if (fields==="" || fields===undefined){
        fields="*";
    }

    if (where==="" || where===undefined){
        where="1=1";
    }

    var coordsArray = location.split(" ");
    var coords = coordsArray[1] + "," + coordsArray[0]

    var xmlhttp = new XMLHttpRequest();
    var url = featureLayer + "/query?geometry=" + coords +  "&where=" + where + "&geometryType=esriGeometryPoint&inSR=4326&distance=" + searchWithinMeters + "&units=esriSRUnit_Meter&outFields=" + fields + "&returnGeometry=true&outSR=4326&f=json"

    if (token){
        url = url + "&token=" + token;
    }

    xmlhttp.open("GET",url,false);
        xmlhttp.send();

    if (xmlhttp.status!==200){
        return (debugmode? xmlhttp.status:"");
    } else {
        var responseJSON=JSON.parse(xmlhttp.responseText)
        if (responseJSON.error){
            return (debugmode? JSON.stringify(responseJSON.error):"");
        } else {
            var count = responseJSON.features.length;
            if (count===0){
                return (debugmode? "No Features Found":"");
            }
            else if (count===1){
                return JSON.stringify(responseJSON.features[0]);
            }
            else if (count>1){
                var nearestIndex = findNearestIndex (location, responseJSON.features);
                return JSON.stringify(responseJSON.features[nearestIndex]);
            }
        }
    }
}

function findNearestIndex(location, features){
    var nearestIndex = 0;
    var minDistance = 999999999999;

    var coordsArray = location.split(" ");
    var lat1 = coordsArray[0];
    var lon1 = coordsArray[1];

    for (let i = 0; i < features.length; i++) {
      var dist = getDistanceKM(lat1,lon1,features[i].geometry.y,features[i].geometry.x);
      if (dist < minDistance){
        minDistance = dist;
        nearestIndex = i;
      }
    } 

    return nearestIndex;
}

function getDistanceKM(lat1, lon1, lat2, lon2) {
    if ((lat1 == lat2) && (lon1 == lon2)) {
        return 0;
    }
    else {
        var radlat1 = Math.PI * lat1/180;
        var radlat2 = Math.PI * lat2/180;
        var theta = lon1-lon2;
        var radtheta = Math.PI * theta/180;
        var dist = Math.sin(radlat1) * Math.sin(radlat2) + Math.cos(radlat1) * Math.cos(radlat2) * Math.cos(radtheta);
        if (dist > 1) {
            dist = 1;
        }
        dist = Math.acos(dist);
        dist = dist * 180/Math.PI;
        dist = dist * 60 * 1.1515;
        return dist * 1.609344;
    }
}

I tried editing the lines myself and I got to the point in survey 123 where it returns this enter image description here my reference inside arcgis survey 123 is:

the code block I have is

function getNearestLabel(filePath, segmentPoint, debugmode) {
    if (!filePath || filePath === undefined) {
        return (debugmode ? "File path is not provided" : "");
    }

    if (!segmentPoint || segmentPoint === undefined) {
        return (debugmode ? "Segment point is not provided" : "");
    }

    var coordsArray = segmentPoint.split(" ");
    var pointLat = parseFloat(coordsArray[0]);
    var pointLon = parseFloat(coordsArray[1]);

    // Assuming data is stored in a JSON file
    var xmlhttp = new XMLHttpRequest();
    var url = "media/scat_segment.json"; // Corrected file path
    xmlhttp.open("GET", url, false);
    xmlhttp.send();

    if (xmlhttp.status !== 200) {
        return (debugmode ? "Failed to fetch data from JSON file" : "");
    } else {
        var responseJSON = JSON.parse(xmlhttp.responseText);
        var nearestIndex = findNearestLineIndex(pointLat, pointLon, responseJSON.features);
        var nearestLabel = responseJSON.features[nearestIndex].attributes.Label;
        return nearestLabel.toString(); // Convert to string before returning
    }
}
