I'm using the following to populate terms on my pages...

  $mget_site_url = get_site_url();

    //This gets me all the correct terms...
    $mget_the_terms = get_the_terms(get_queried_object_id(), 'ht_kb_tag');
    echo __( 'Tagged: ', 'knowall' );
    foreach ($mget_the_terms as $keygroup => $valuegroup) {
        foreach ($valuegroup as $key => $value) {
            if (($key == 'name') && ($value != 'layout-wide')) {
                //link the terms
                echo "<a href='{$mget_site_url}/tags/{$value}' rel='tag'>{$value}</a>";
            }
        }
    }

How can I conditionally cancel this process if the page does not have any terms? Trying to avoid the foreach error I'm seeing.

Many thanks!

hide_empty hides terms that have no posts attached to them. You've got a page with no ht_kb_tags attached to it, if I'm understanding the question correctly.

Since get_the_terms() returns false if there are no terms, you should be able to prevent the foreach() with an if() statement:

$mget_site_url = get_site_url();

//This gets me all the correct terms...
$mget_the_terms = get_the_terms(get_queried_object_id(), 'ht_kb_tag');
if ( ! empty( $mget_the_terms ) ) {
    echo __( 'Tagged: ', 'knowall' );
    foreach ($mget_the_terms as $keygroup => $valuegroup) {
        foreach ($valuegroup as $key => $value) {
            if (($key == 'name') && ($value != 'layout-wide')) {
                //link the terms
                echo "<a href='{$mget_site_url}/tags/{$value}' rel='tag'>{$value}</a>";
            }
        }
    }
}
