Cannot read property 'data' of null how to solve the problem?

Question

JavaScript

I'm trying to add an event object to the trigger.

.trigger({type: 'keydown', keyCode: 13, ctrlKey: true})

To pass into the condition

element.on('keydown', (_event) => {
                            if (_event.keyCode == 13 && _event.ctrlKey) {

As a result, it gives me an error
TypeError: Cannot read property 'data' of null
