Get ID of a page containing secondary loop in content

I am trying to get the ID (outside of loop) of a page which have a loop of another CPT within its content using a shortcode.

If I do a print_r of get_queried_object(), all I get the args used to register the CPT
If I echo $post->ID I get the ID of the last item in the secondary loop.
If I echo get_queried_object_id(), I get 0 all the time.

Here is the code I am currently using

function get_meta_values() {
    global $post;
    $queried_object = get_queried_object();
    echo '<pre>';
    print_r( $queried_object ); //Returns args used to register the CPT
    echo '<br> $queried_object->ID: ' . $queried_object->ID; //Returns Nothing
    echo '<br>get_queried_object_id(): '. get_queried_object_id(); // Returns 0 all the time
    echo.'<br>PageID: ' . $post->ID; // Returns the ID of last item in the secondary loop
    echo '</pre>';

}
add_action( 'wp_footer', 'get_meta_values' );  

My goal is to get the ID of the page (where the shortcode is) to retrive some custom field values.

EDIT: I am using WooCommerce, but the shortcode that outputs the products is custom. I know I could bypass the issue by other means, but just curious why this is not working.

As others figured already out: If you have third party plugins with custom queries, you’ll have a bad day!

One solution might be caching your results.

Template (e.g.: page.php)

while (have_posts()): the_post();
    global $my_cached_data;
    $post_id = get_the_ID();
    /* 
     * If you have single meta keys, this array_map function 
     * makes them easy to access; otherwise just use:
     *
     * $my_cached_data[$post_id] = get_post_meta( $post_id) 
     */
    $my_cached_data[$post_id] = array_map( 
        function( $a )
        { 
            return $a[0]; 
        }, 
        get_post_meta( $post_id) 
    );
endwhile;

footer.php

global $my_cached_data;
echo "<pre>".print_r($my_cached_data, true)."</pre>";

Possible Result (with Page ID 2 and 15 having the same post meta data)

array(2) {
  [2]=>
  array(2) {
        ["meta_key"]=>
    string(10) "meta_value"
        ["another_key"]=>
    string(10) "meta_value"
  }
  [15]=>
  array(2) {
        ["meta_key"]=>
    string(10) "meta_value"
        ["another_key"]=>
    string(10) "meta_value"
  }
}
