Image not replacing with variation image - php

Question

I am trying to create a function which replaces the head image with the variation image clicked. I did make a function but I am getting an error in the console. Here is the function:
// add this to functions.php
add_action('woocommerce_after_single_product','custom_woocommerce_additional_variation_images');
function custom_woocommerce_additional_variation_images(){
?>
<script type="text/javascript">
(function($) {
$(window).load(function(){
$( "a.swatch-anchor").click(function() {
//console.log(variation);
var atts = $(this).parent().attr('data-value');
var product_variations = $('form.variations_form').data('product_variations');
console.log(product_variations);
var variation_id = '';
for ( var i = 0; i < product_variations.length; i++ ) {
var variation = product_variations[i];
if( product_variations[i].attributes.attribute_pa_kleur == atts){
variation_id = product_variations[i].variation_id;
}
}
console.log(variation_id);
var data = {
security: wc_additional_variation_images_local.ajaxImageSwapNonce,
variation_id: variation_id,
post_id: $( 'form.variations_form' ).data( 'product_id' )
};
$.ajax({
type: "POST",
url: $.wc_additional_variation_images_frontend.getAjaxURL( 'get_images' ),
data: data,
cache: false,
success: function(data,response){
data = $.parseJSON(data);
console.log(data['main_images']);
$('.woocommerce-product-gallery').replaceWith(data['main_images']);
},
});
});
})
})(jQuery);
</script>
<?php
}
add_filter( 'wc_additional_variation_images_custom_swap', '__return_true');
add_filter( 'wc_additional_variation_images_custom_reset_swap', '__return_true' );
add_filter( 'wc_additional_variation_images_custom_original_swap', '__return_true' );
add_filter( 'wc_additional_variation_images_get_first_image', '__return_true' );
The console is returning: Uncaught ReferenceError: wc_additional_variation_images_local is not defined
Here is the website which I am using: https://www.dev.ruitershopboxmeer.nl/product/kingsland-zadeldekje-carin/
Does anyone know what I am doing wrong?
