Get a ACF field using get_pages()

I'm displaying a list of sibling pages using the below code. As well as retrieving the page title and link. I need to grab a custom field called excerpt and output it for each sibling item. How do I do this using get_pages? Currently the var_dump I'm using is grabbing the current pages excerpt, which is incorrect.

<?php
    global $post;
    if ( is_page() && $post->post_parent ) {

        $children = get_pages('child_of='.$post->ID);
        $parent = $post->post_parent;
        $our_pages = get_pages('child_of='.$parent.'&exclude='.$post->ID);
        $ex = get_field('excerpt', $our_pages);

        if (!empty($our_pages)):
            foreach ($our_pages as $key => $page_item):
                <a href="<?php echo esc_url(get_permalink($page_item->ID)); ?>" title="<?php the_title(); ?>">
                    <?php echo $page_item->post_title ; ?>
                    <?php var_dump($ex) ?>
            <?php endforeach;
        endif;

    }

UPDATE

Ok so I have put in <?php print_r($page_item); ?> as suggested and it has returned the following:

I don't see any of my ACF fields here, so how do I retrieve those? What are my next steps?

I've got the same problem with AFC and get_pages().

Try to access ACF fields by retrieving all posts by page type.

$args = array(
 'post_type' => 'page',
 'numberposts' => -1,  // Accepts -1 for all. Default 5.
);

$pages = get_posts($args);

Now ACF get_field('excerpt'); function will work, because get_pages() doesn't return all needed data.

If you'd like to get specific pages like siblings you could pass theirs id's as get_posts() 'include' argument (arr).

Read more about get_posts() in documentation.

You full code like below:

<?php
global $post;
if ( is_page() && $post->post_parent ) {

    $children = get_pages('child_of='.$post->ID);
    $parent = $post->post_parent;
    $our_pages = get_pages('child_of='.$parent.'&exclude='.$post->ID);
    $ex = get_field('excerpt', $our_pages);

    if (!empty($our_pages)):
        foreach ($our_pages as $key => $page_item):
            <a href="<?php echo esc_url(get_permalink($page_item->ID)); ?>" title="<?php the_title(); ?>">
                <?php echo $page_item->post_title ; ?>
                <?php echo get_post_meta( $page_item->ID, 'excerpt', true); ?>
        <?php endforeach;
    endif;

}

If you didn't get the data like above then change you custom filed name with any other name and then try.

You should be using the_field(), or echo get_field(), within your forloop, and should pass the post ID as the second parameter of the function:

if (!empty($our_pages)):
    foreach ($our_pages as $key => $page_item):
        <a href="<?php echo esc_url(get_permalink($page_item->ID)); ?>" title="<?php the_title(); ?>">
            <?php echo $page_item->post_title ; ?>
            <?php the_field('excerpt', $page_item->ID); ?>
        </a>
    <?php endforeach;
endif;

You can read more about how get_field() works, in the documentation.
