First step, you’re in a function so you need to declare the global $post.

If that does not work the add the post id to the function calls instead of letting WP try to figure them out. I’d probably do this anyway.

add_action( 'init', 'copy_data' );
function copy_data() {
	if ( !is_admin() )
		return;
	
	// declare global, you cant access $post without it
	global $post;
	
	// WP_Query arguments
	$args = array (
		'post_type'              => array( 'ze_event' ),
	);
// The Query
$query = new WP_Query( $args );

// The Loop
if ( $query->have_posts() ) {
	while ( $query->have_posts() ) {
		$query->the_post();

		update_field( 'field_56b4d48d4b471', get_the_content($post->ID), $post->ID );
		
	}
} else {
	// no posts found
}

// Restore original Post Data
wp_reset_postdata();

}
