Migrating bootstrap to v4 - popovers not working

Question

I have problem with migrating Bootstrap from version 3 to 4. The problem is with popovers and the popper.js library. Every time I hover on an element I get this error:

Uncaught TypeError: Cannot read property 'indexOf' of undefined

at v (computeAutoPlacement.js:24) at Object.onLoad (applyStyle.js:57) at index.js:69 at Array.forEach () at new t (index.js:67) at i.t.show (tooltip.js:286) at HTMLSpanElement. (popover.js:166) at Function.each (jquery.min.js:2) at r.fn.init.each (jquery.min.js:2) at r.fn.init.i._jQueryInterface [as popover] (popover.js:149)

Libraries I used:

<script src="https://code.jquery.com/jquery-3.2.1.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q" crossorigin="anonymous"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"></script>

And Angular 1.6

This is how the element looks like:

<span class="tip-icon m-r-0" data-toggle="popover" data-content{{item.info}}" ng-if="item.info">Tooltip</span>
                                       

And this is how it is set in the controller:

$('[data-toggle="popover"]').popover({
    trigger: 'hover',
    animation: false,
    html: true
});

When I migrate back to Bootstrap 2.3.2 everything works fine.

Any idea about what is causing the problem? Thank you in advance!

I've faced the same problem and found solution, here is my popover directive

angular
.module('app.ui.popover', [])
.directive('bsPopover', function () {
    return {
        restrict: 'E',
        replace: true,
        template: '<span class="a-info" ng-bind-html="label"></span>',
        link: function (scope, element, attrs) {
            var el = $(element);
            el.popover({
                container: 'body',
                trigger: attrs.trigger || 'hover',
                html: true,
                animation: false,
                content: attrs.content,
                placement: attrs.placement || 'auto top'
            });
        }
    };
});

and what I did next was changing default placement from 'auto top' value to 'top' and it works for now :)

As far I understood, now you can specify only one of auto | top | bottom | left | right.

Let me know if that helps you :)
