Welcome to the Make community!
This is because the module is a POLLING trigger, and not an INSTANT (Webhook) trigger.
There are two main types of triggers, Polling (scheduled), and Instant (webhooks). Polling triggers can only run on a schedule. Instant triggers can be run as soon as data is received by the webhook.
Polling means Make checks external service for changes (pull changes to Make).
Webhook (instant) triggers means external service calls Make when there are new changes (push changes to Make).
The module you are using does not push changes — it’s basically a API request that Make has to occasionally “call” to fetch the latest changes/items.
To find out more on the different types of Trigger modules, see refer to Types of Modules and Webhooks sections of the Make help center.
So it doesn’t “die”, there are just no new results returned.
