I would like my Notehub route to include only ‘Open’ Notecard session data and exclude ‘Closed’ session data. What type of expression should I use in the JSONata transform field to accomplish this?

To exclude ‘Closed’ session data from your existing Notehub route, navigate to the **Data** section in your route settings. In the **Transform Data** dropdown, select **JSONata Expression**. In the **JSONata Expression** field, enter the following expression:

```auto
(
$result := $;
$contains(body.why, "closed") ?
$doNotRoute() : $result;
)

```
