When activating in conflict with Vegas slider

Hello, when I am activating the plugin, another part of my website (my Slider Vegas, not a WP plugin but manually made due to the custom fields in the slider) is getting conflicts. In developer tools I get the message:

Uncaught TypeError: $(...).vegas is not a function

When I turn the 301 plugin off the slider works fine again so there is a conflict but I really don’t know where. I call the slider within my WP template via:

<script type="text/javascript">
	(function($){
		$(document).ready(function(){
			$("body").vegas({
			...
			});
		});
	})(jQuery);
</script>

I hope you guys have an idea whats going wrong.

Edit: kinda stupid, I forgot to mention that my slider is being pulled upon the body. It’s the only bug of this slider that it can’t be put into a div with a class of id so I am forced to use my body tag to pull up the slider… Is there a way the 301 plugin can still be used since it is also using the body tag?
