jQuery Bootstrap Toggle - Uncaught Error: Syntax error, unrecognized expression: # at Function.Sizzle.error

Question

I am using Jquery 3.3.1 and Bootstrap 3.3.7 pulled via npm.

I have the following markup to toggle a div:

<div class="text-right">
     <a class="js-accordion-trigger" data-toggle="collapse" href="#advanced-search" aria-expanded="false" aria-controls="advanced-search">Advanced search <span class="js-notifier"></span></a>
</div>

<div id="advanced-search" class="js-accordion-content collapse">

</div>

However I am now getting the following error in console:

libs.js:1541 Uncaught Error: Syntax error, unrecognized expression: #
at Function.Sizzle.error (libs.js:1541)
at Sizzle.tokenize (libs.js:2193)

I also encounter a similar issue, though it's not a show stopper.

it is when I created a button that would invoke a modal to show up, something like the code below.

<a href="#" id="btnMyButton" data-toggle="modal" onclick="myFunction()" data-dismiss="modal">

It looks like the cause is the following attribute:

href="#"

Replacing it with the attribute below removes shown error

href="javascript:void()"
