Seeing console error, favorites never load

[jacksonp2008]

PHP Version 7.4.33
Wordpress: 6.1.1
Chrome or Edge on MAC

Tried disabling cache on bluehost and disabling endurance page cache plugin but no change. Buttons appear in loading state and the totals never update: user favorites and post favorites

Seeing this error as well:

Any suggestions?

Also in error log:
[31-Mar-2023 18:03:43 UTC] PHP Notice: Undefined variable: site_id in /home2/qkqazymy/public_html/wp-content/plugins/favorites/app/Listeners/FavoriteList.php on line 49

And in debug mode we see a failed post.

Don't everyone jump on this at once..

Ran into this same error. Traced it back to failing validation due to an invalid post type. I had to go to the settings and set the post types to enable Favorites for.
