Problem on remove a suscription

Hi!

When I tried to remove a subscription created via WooCommerce Subscription, I got this error:
Fatal error: Uncaught Error: Attempt to assign property “comment_status” on null
in /wp-content/plugins/zoho-flow/integrations/wordpress-org/wordpress-org.php on line 470

Searching in the code I saw:

 $comment = get_comment($comment_id);
$comment->comment_status = $comment_status;

Maybe you might do:

$comment = get_comment($comment_id);
if ( $comment ) { return; }
$comment->comment_status = $comment_status;

The problem is when $comment_id is null, and the hook is called.
Can you resolve this?
Thanks!
Cheers!
