Hello, I’ve got a teaser snippet that pulls the taxonomy info for a custom post type and works fine when using a wpquery:

setup_postdata($post);
$postid = $post->ID;
$item_image = get_field("listing_image", $post->ID);

    // TAXONOMY //
    $taxonomy = 'types';
    $terms = get_object_term_cache( $postid, $taxonomy );
    $outputpill = '';
    $i = 1;

    $teasertype = '';
    foreach($terms as $term) {
        if ($i == 2) { break; }
    if(!empty($outputpill))
        $outputpill .= '';
        $outputpill .= '<div class="cat cat-pill pill-'. $term->slug . '">'.$term->name.'</div>';
        $teasertype = $term->slug;{}
        $i++;
   
    }

    // BUTTON SWITCH //
    if($teasertype){
    switch($teasertype){  
        case 'article':
            $ctaclass= "article";
            $ctatext= "Read Now";

etc etc etc 

When I use this snippet on another page that references these custom post types using a Post Object field, it throws an error when looking up the taxonomy:

Warning
: foreach() argument must be of type array|object, bool given in

Code used:

									<?php $post_objects = get_field('campaign_group1_item_resource'); ?>
									<?php
									if( $post_objects ):
									foreach( $post_objects as $post): 
										setup_postdata($post); //set new $post_object
										get_template_part( 'inc/snippets/_incl_resources--teaser' );
									endforeach;
									wp_reset_postdata(); //reset global $post
									endif;
									?>
