Uncaught TypeError: Cannot read property 'call' of undefined at __webpack_require__

Question

I am using React.lazy to load some React classes on runtime so that they are not all loaded at once. My code works for production, but crashes when I am in development mode.

Answer 1

I was able to fix this by changing

map.on('moveend', update());

to

map.on('moveend', function () {
    update();
});
