Getting the above error in chrome.

i'm using browserfy to bundle my js so in my packages.json i have the following

"browser": {

"jquery.easings": "./src/libs/jquery.easings.min.js",
"multiscroll": "./src/libs/jquery.multiscroll.js"

},

Then in my js i'm doing

`import "jquery.easings";
import "multiscroll";

var Home =
{
"Init": function () {
$("#multiscroll").multiscroll();
},
};

module.exports = Home;`

any idea why this error is showing? seems to function fine even with it. thanks

Just to add to this, this error is stopping the navigation active class being removed and applied to the current slide.
