Component error on Trailhead Geolocation app

Hello,

I am completing the Develop an Account Geolocation App with Aura Components Trail on Trailhead and though my components are functioning properly, every time I write something in the search bar (to query accounts) i get the following error

User-added image
The error seems to be coming from the following controller in the "AccountMapController" class
  
({
    onAccountsLoaded: function( component, event, helper ) {
        var mapMarkers = [];
        var accounts = event.getParam( 'accounts' );
        for ( var i = 0; i < accounts.length; i++ ) {
            var account = accounts[i];
            var marker = {
                'location': {
                    'Street': account.BillingStreet,
                    'City': account.BillingCity,
                    'PostalCode': account.BillingPostalCode
                },
                'title': account.Name,
                'description': (
                    'Phone: ' + account.Phone +
                    '<br/>' +
                    'Website: ' + account.Website
                ),
                'icon': 'standard:location'
            };
            mapMarkers.push( marker );
        }
        component.set( 'v.mapMarkers', mapMarkers );
    }
})

The issue seems to be with this accounts.length; 
What is length? it is not a custom field? is it the size of the Accounts list?

Any help to prevent this error would be great. I am trying to adapt this for my business
