Uncaught TypeError: Unsupported operand types

I got the same error. Some minor change can fix this. Can you please alter the function?

	private function check_update_validity( $wc_order ) {
		$ac_datahash      = $wc_order->get_meta( 'ac_datahash' );
		$current_datahash = md5( json_encode( $wc_order->get_data() ) );
		$last_synced      = $wc_order->get_meta( 'ac_order_last_synced_time' );
		$last_status      = $wc_order->get_meta( 'ac_last_synced_status' );
		$currentstrtotime = time();

		if (
		( ( $currentstrtotime - intval( $last_synced ) ) > 120 ) &&
		isset( $last_status ) &&
		$last_status === $wc_order->get_status() &&
		$ac_datahash === $current_datahash
		) {
			return false;
		}

		return true;
	}

I see this on the latest version, so it should be fixed now…
if ( ! empty( $last_synced ) && time() - intval( $last_synced ) < 120 ) {
Thank you!
