Trying to get access to admin-ajax.php but failing

Hello,

I’m having some trouble getting access to admin-ajax.php via admin_url and I get 400 Bad Request every time. Have looked at some posts in this forum but still can’t get why it’s not working :confused:

My setup.php looks like this:

add_action('wp_enqueue_scripts', function () {

    wp_enqueue_style('sage/main.css', asset_path('styles/main.css'), false, null);
    wp_enqueue_script('sage/main.js', asset_path('scripts/main.js'), ['jquery'], null, true);
    wp_enqueue_script('sage/ajax-pagination', asset_path('scripts/ajax-pagination.js'), ['jquery'], null, true);

    wp_localize_script( 'sage/ajax-pagination', 'sage', array(
        'ajax_url' => admin_url( 'admin-ajax.php' )
    ));
    if (is_single() && comments_open() && get_option('thread_comments')) {
        wp_enqueue_script('comment-reply');
    }
    
}, 100);

And then I have added an ajax.js script which I will use and it looks like this:

$(document).on( 'click', '.nav-links a', function( event ) {
    event.preventDefault();
$.ajax({
	url: window.sage.ajax_url,
	type: 'post',
	data: {
		action: 'ajax_pagination'
	},
	success: function( result ) {
		alert( result );
	}
    })
})

So whenever I click the .nav_link I only get a "Failed to load resource: the server responded with a status of 400 (Bad Request) from localhost:3000/wp-admin/admin-ajax.php.

Does anyone have any idea what I’m doing wrong? Thanks in advance!

Try this: Wp_localize_script not working in Sage 9?
