Error: Uncaught TypeError: Cannot read property 'getTemplate' of undefined (Line 18)

When trying to use this with Summernote, I am getting the error above in the console. Here is my JS:

$(document).ready(function(){
        $content.summernote({
            prettifyHtml:false,
            codemirror: {
                theme: 'default',
            },
            toolbar:[
                ['highlight', ['highlight']],
            ],
        });

    });

And here is the loading order of my assets:

Any idea what may be causing this?
