Finding Post ID in Gutenberg Block Templates within WordPress Preview

So I have discovered that you need to pull in

get_the_ID();

And reference it within any calls to ACF’s
the_field('fieldname',get_the_ID());

in order to have a Gutenberg Block template accurately display ACF, as it seems that the ID has been flipped to the Block ID (and I totally get why).

My issue is that I cannot get the Post ID (no way, no how) within the template so that the preview that is displayed within WordPress and Gutenberg is accurate. The functions

get_the_ID();

and

global $post;
$post = $post_object;
setup_postdata($post);
print 'Post: ' . $post->ID; 

Both come up with no values within the preview in WordPress/Gutenberg. It absolutely works when printing out the actual live page, but it doesn’t show anything within the WordPress interface.

Any idea how to grab the Post ID within a Gutenberg Block template so that I can grab some ACF fields? ACF fields populate just fine if I feed it a static Post ID, I just can’t find a way to feed it the current Post ID.

Adding this function will solve the issue (compliments of another poster):

function my_acf_post_id() {
	if ( is_admin() && function_exists( 'acf_maybe_get_POST' ) ) :
		return intval( acf_maybe_get_POST( 'post_id' ) );
	else :
		global $post;
		return $post->ID;
	endif;
}
