Display Products Associated with Specific Attribute [closed]

Error in wc_get_products caught by @SallyCJ fixed my problem.

Where I had ingredients, I needed pa_ingredients.

Working code is as follows:

$taxonomy = 'pa_ingredients';
$terms = get_terms( $taxonomy );
foreach ( $terms as $term ) {
    $products = wc_get_products( array( 'pa_ingredients' => $term->slug ) );
    foreach ( $products as $product ) {
        $product_id = wc_get_product_id_by_sku( $product->sku );
        $link = get_permalink( $product_id );
        echo '<a href="' . $link . '">' . $product->name . '</a>';
    }
}

Thanks!
