aurelia error (0, _bootstrap2.default) is not a function

Question

I have an aurelia app for a filmfestival and recently I stumbled upon an error that I don't understand. I have a line of code:

const timetableElement = $('<div>').attr('id', timetableID).addClass('timetable anim-fade-in');

That after compiling it changes to

var timetableElement = (0, _bootstrap2.default)('<div>').attr('id', timetableID).addClass('timetable anim-fade-in');

Which result in the error: (0, _bootstrap2.default) is not a function.

I hope I made myself a bit clear.
