Hey this function format_menu_item just gets the slug for posts/pages but not for terms. I changed the function to get it for terms as well. @metazoa-org I hope you can include this in an update.

        public function format_menu_item( $menu_item, $children = false, $menu = array() ) {

            $item = (array) $menu_item;

            $object_slug = '';
            if($item['type'] == 'taxonomy'){
            	$term = get_term($item['object_id'], $item['object']);
            	$object_slug = $term->slug;
            }else{
            	$object_slug = get_post( $item['object_id'] )->post_name;
            }
            
            $menu_item = array(
                'id'          => abs( $item['ID'] ),
                'order'       => (int) $item['menu_order'],
                'parent'      => abs( $item['menu_item_parent'] ),
                'title'       => $item['title'],
                'url'         => $item['url'],
                'attr'        => $item['attr_title'],
                'target'      => $item['target'],
                'classes'     => implode( ' ', $item['classes'] ),
                'xfn'         => $item['xfn'],
                'description' => $item['description'],
                'object_id'   => abs( $item['object_id'] ),
                'object'      => $item['object'],
                'object_slug' => $object_slug,
                'type'        => $item['type'],
                'type_label'  => $item['type_label'],
            );

            if ( $children === true && ! empty( $menu ) ) {
	            $menu_item['children'] = $this->get_nav_menu_item_children( $item['ID'], $menu );
            }

            return apply_filters( 'rest_menus_format_menu_item', $menu_item );
        }

Better yet, use a filter to add the slug to a category menu point:

<?php 
// fix for: https://github.com/unfulvio/wp-api-menus/issues/42

add_filter('rest_menus_format_menu_item', function($item){
    if($item['type'] == 'taxonomy'){
        $term = get_term($item['object_id'], $item['object']);
        $item['object_slug'] = $term->slug;
    }
    return $item;
}, 10, 1);

Hi,

I have a similar issue with a menu item where the type is post_type_archive. This is a page from a plugin.

It triggers a notice at the top of the response which makes it "invalid" for the consumer:

< br / > < b > Notice < /b>:  Trying to get property of non-object in <b>/[...]/wp-content/plugins/wp-api-menus/includes/wp-api-menus-v2.php < /b> on line <b>386</b > < br / > {
    "ID": 2,
    "name": "Main",
    "slug": "main",
[...]

I think this is related to this issue because the code assume that get_post( $item['object_id'] ) will return something whereas get_post can an will return null if the post is not found for some reason.

I've made a hotfix branch on my fork here but I believe that it can be improved before making a pull request here.

What are all the type that can be post_type, custom, taxonomy ? Let's see if we can handle them all ⚗️ !

PS: The given filter does not work because it's done after the item has been formatted and the notice is triggered/added no matter what 😞 .

both post archive and taxonomy terms are fixed in this repo. I raised a PR but i feel the author has abandoned this plugin.
