Bootstrap 5 – Uncaught TypeError: Popper__namespace.createPopper is not a function

by

I received this error (TypeError: i.createPopper is not a function) each time when popovers should be shown. Previously I had to make use of the Separate Popper and Bootstrap JS (Option 2) – due to conflict with other scrips. However this is no longer necessary in my project, with Bootstrap 5.1.1.

Including only the Bootstrap bundle with popper – as per @Kevin’s comment above – fixed the issue for me – And the previous conflicts don’t seem to be an issue anymore. All popovers, tooltips, modals, sidebars etc. seem to now be working properly:

<body>
    <!-- Option 1: Bootstrap Bundle with Popper -->

</body>
