Cornerstone does not work, mrdplusd quick fix worked for couple hours

"I applied this quick fix this afternoon and it worked:

$items = json_decode( wp_remote_retrieve_body( $request ), true );

if ( ! is_array( $items ) ) {

$items = [];

}

$items = array_filter( $items, function( $item ) {

if ( ! is_array( $item ) ) return false;

if ( ! $this->validLegacyType($item) ) return false;

if ( empty( $item[‘status’] ) ) return false;

if ( $item[‘status’] !== ‘publish’ ) return false;

return true;

} );

However, it’s no longer working. On the advice of @charlie, I’m starting a new topic for this.
