More context:
I’m using the latest version, 5.8.7 with WordPress 5.2.X
When performing a live search in an ACF relationship field in the admin section, admin-ajax.php is called.
On my local dev environment, I can search in that box and have results returned. Even if there are no results, I receive this:
{"results":[],"more":false,"limit":0}
On production, if I search, all I ever receive is (results or not) an empty string.
wp_debug doesn’t log an error.
