Everything worked and suddenly there was a mistake Cannot read property 'entries' of undefined that it could be ? (including googlemaps api)

Uncaught TypeError: Cannot read property 'entries' of undefined at js?key=<API_KEY>&callback=Map.init:105

Map.init

    Map.init = function (id) {
    id = id || 'map';
    map = new google.maps.Map(document.getElementById(id), {
        center: {lat: 46.409998, lng: 30.710000},
        scrollwheel: true,
        zoom: this.address ? 20 : 12
    });

    infoWindow = new google.maps.InfoWindow();

    map.addListener('zoom_changed', function () {
        var zoom = map.getZoom();
        if (zoom > zoomShowPoints && !pointsVisibility) {
            pointsVisibility = true;
            points.forEach(function (item) {

• You need to add the code related to the problem. The error is that you are trying to read the property entries from an object or something, but in the there's no reference to entries anywhere in the code that you shared. I'd remend you to read How to Ask and minimal reproducible example. – Alvaro Montoro Commented Sep 14, 2017 at 16:24
• I know why he didn't add the code: this error is happening in the maps.googleapis./maps/api/js endpoint; so it seems to be a Google Maps issue. It's happening to me right now. – Phillip Gruneich Commented Sep 14, 2017 at 20:52

• 2 Problen was in the name of the variable I used. The name of variable was "var Map", so i changed the name and error has gone – Арсен Гзирян Commented Sep 15, 2017 at 16:52

Google changed their Maps API script November 2017. They started using global variable Map which broke our site. Renaming the Map variable to OurMap in our script fixed the issue.

var Map;

changes to;

var OurMap;

it was solved by adding version param
