Getting Cannot read property 'offsetWidth' of undefined with bootstrap carousel script

For me it was because I hadn't set an active class on any of the slides.

For me, I changed class='carousel-item' to class='item' like this

<div class="item">
    <img class="img-responsive" src="..." alt="...">
</div>

Remove the class 'Carousal slide' on page load & add it dynamically when image gets loaded using jquery.This fixed for me
