I have a problem with fullcalendar script. I cant get attributes of clicked divs. I need to get id attribute of an external event

this is the div

<div id="1303" class="fc-event"  data-color="#9900cc">
<span class="mr-1 badge bg-orange" style="width: 5%; padding-left: 0px;padding-right: 0px;">-26</span>Some text
</div>

this is the code on click

$('#external-events').on('click', '.fc-event', () => {
    const element = $(this);
    console.log(Object.keys(element));
    console.log(Object.values(element));
    console.log(Object.entries(element));
})

and this is the result

How can i get attributes of these divs(there are more that 1)? Where is my mistake? if i do element.attr('id') i get 'undefined'

Thanks in advance
