Event click error in indexOf property in picker.js file

This error happen using a node app, in the web app work perfectly. When an event click occurs with the picker the function "getRealEventTarget" receive the event and the element.
`function getRealEventTarget( event, ELEMENT ) {

var path = []

if ( event.path ) {
path = event.path
}

if ( event.originalEvent && event.originalEvent.path ) {
path = event.originalEvent.path
}

if ( path && path.length > 0 ) {
if ( ELEMENT && path.indexOf( ELEMENT ) >= 0 ) {
return ELEMENT
} else {
return path[0]
}
}

return event.target
}`
In the node app the variable path is not an array but a nodeList and nodeList don't have the property "indexOf" giving in the consle the error "undefined is not a function" and stop executing the next code and ,in my case, preventing me from closing the calendar keeping it open.
