I hit this myself just now and found that it's due to not including the bootstrap script itself. I copied the bootstrap include from the index.html example in the repo and was able to move past (the CSS is really messed up for me at the moment but I'm past this, it's working, and I think I can get the CSS resolved by other things).

The example line I copied from the repo:

<script src="//stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js" integrity="sha384-B4gt1jrGC7Jh4AgTPSdUtOBvfO8shuf57BaghqFfPlYxofvL8/KUEfYiJOMMV+rV" crossorigin="anonymous"></script>

I also had an issue with needing to include JQuery prior to this.

These things are likely obvious to most people who go to use bootstrap-autocomplete, but I'm a backend developer, so while I can recognize it should have been obvious to me, adding a line in the documentation to specifically say this is probably a good idea.

I may get around to making the one or two line doc PR to add that.
