Object in console.log differs from object properties accessible in code

Question

I'm using Highcharts to create some charts on the page. I'm trying to use the customEvents plugin to add functionality to a bubble click (pop up a modal when bubble clicked). I know Highcharts can do this without a plugin, but I need to add other functionality to other charts on the page, and only the plugin provides that functionality. So here's the issue:

I successfully added an event handler function to bubble click. It looks like this:

            plotOptions: {              
            series: {                           
                dataLabels: {
                    enabled: true,
                    format: '{point.projectId}',
                    events: {
                        click: function (event) {
                            console.log("Evt:",event); // event.point has what I need
                            console.log(event.point); // undefined

                            $('#modalTable2').dataTable().fnClearTable();
                            $('#modalTable2').dataTable().fnAddData([event.point.x,event.point.y,event.point.z]);
                            $('#modal2').modal('show');
                        }
                    }
                },
            },
            bubble: {
                marker: {enabled:true},
                threshold: -10,
            }
        },

As stated in the code comments, I can see event.point in the properties in the Javascript console, but it's not actually accessible/defined in code. How can I access this object?
