Getting error in android. while onEnterAction event is triggered.

 onZoneEntered = context => {
        if (!this.props.isInCheckOutFlow) this.getCurrentStore();
        console.log('zone1 onEnter', context);
    };

    onZoneExit = context => {
        console.log('zone1 onExit', context);
    };

    onZoneChanged = contexts => {
        console.log('zone1 onChange', contexts);
    };

    componentDidMount() {
        RNEP.locationPermission.request().then(
            permission => {
                if (permission !== RNEP.locationPermission.DENIED) {
                    const credentials = new RNEP.CloudCredentials(ESTIMOTE_APP_ID, ESTIMOTE_APP_TOKEN);
                    const config = {
                        notification: {
                            title: 'Exploration mode is on',
                            text: "We'll notify you when you're next to something interesting.",

                        {
                            tag: 'shop1'
                        },
                        {
                            tag: 'shop2'
                        }
                    ];
                    var zones = [];
                    for (var i = 0; i < beaconList.length; i++) {
                        var zone = new RNEP.ProximityZone(5, beaconList[i].tag);
                        zone.onEnterAction = this.onZoneEntered;
                        zone.onExitAction = this.onZoneExit;
                        zone.onChangeAction = this.onZoneChanged;
                        zones.push(zone);
                    }
                    RNEP.proximityObserver.initialize(credentials, config);
                    RNEP.proximityObserver.startObservingZones(zones);
                }
            },
            error => {
                console.error('Error when trying to obtain location permission', error);
            }
        );

this is code i use to detect beacons. once it detects the beacon I'm getting this error undefined is not an object(evaluating 'n.get(e.zoneId).onEnterAction')

@heypiotr any solutions?

Are you sure you're on 0.5.0? This was an error that happened in earlier versions when you didn't stop the observer properly before starting it again. In 0.5.0, it should instead give you a warning:

It works after updating the package. Thanks!
