### What are you trying to achieve? I try to setup a automation for creating database entries in notion but somehow i have a weird issue when i start i choose for item 1 - Watch database items and then from there i build my automation. The first time i add the “database item” and i do “run once” it shows perfectly all data in it and also the automation runs smoothly. ATM the first time when i build the scenario everything goes well. But after the first time (so from 2nd time and forward) i press the run once button it seems like the current database is empty and stop loading the data in in and it shows a weird 1 on top and i can not test any further things cause the run once button not run the process anymore and keep giving me the “1”. When i keep pushing the run once button it sometimes loads maybe 40% more but then it stops again without any error notice. So somehow it only runs 1 time my process and then it stops. If i remake everything again it works 1 time and then i get the same issue over and over again. ### Steps taken so far 1. Select APP - Notion 2. Connect database 3. Apply on all 4. Run 1 time 5. Works perfect also the automation works perfect 6. From second try the operation data seems missing in step 1. ### Screenshots: scenario setup, module configuration, errors ![Scherm­afbeelding 2024-08-16 om 15.07.42.png](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/9/c/9c7661ded61d86ca4d7ae5c75ce77700d414bf25.png) ![Scherm­afbeelding 2024-08-18 om 15.36.20.png](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/c/6/c6416d56f663be01496df65f00dcf9d1e0315926.jpeg) ![Scherm­afbeelding 2024-08-18 om 15.41.52.png](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/2/2/22835d44fd61c4c2d2fa2011c9f4da8b6292b4d8.png) ![Scherm­afbeelding 2024-08-18 om 15.35.44.png](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/4/7/479d16af94037bad398f23f079fcd227c31ffa68.png) ![Scherm­afbeelding 2024-08-16 om 15.07.00.png](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/9/7/97e5ebb028dabd8f3e26a459eb1f63ee2842ba0d.png) ![Scherm­afbeelding 2024-08-18 om 15.41.47.png](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/9/2/9258ea0b08a3d51aa6f6c4e97457451692da8331.png) ![Scherm­afbeelding 2024-08-16 om 15.06.57.png](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/e/4/e4822f0dcb213690c6b42896d8ce8f2676a69306.png) ---

## Polling Triggers & Empty “Check Runs” This is because the module is a POLLING trigger, and not an INSTANT (Webhook) trigger. If you don’t see any operations after the trigger module, it means there are no **new** responses (empty output bundle) when the scenario ran to check for new items. This is called a “Check run”. 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](https://www.make.com/en/help/modules/types-of-modules#triggers-935210) and [Webhooks](https://www.make.com/en/help/tools/webhooks) sections of the Make Help Centre. If you want your scenario to only run when there is new data (and not on a schedule or timed interval), see if your app has an “Instant” or “Webhook” trigger in Make. If not, check if the third-party service has a feature that can send out a webhook when content is created/updated - and then you can point it to a “Custom Webhook” trigger in your scenario. If you want to re-run your scenario on older data, ## Polling Triggers: Epoch Panel & Selecting Older Data Go to the Epoch Panel, by right-clicking on the trigger module (polling triggers only), and select “ **Choose where to start** ” from the list of options in the context menu. ![](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/5/7/57483f7050599b092d328cdc2a96b8c38a45cfef.png) If you select “ **From now on** ”, the next time the scenario runs it will only return new data (or nothing if there is no new data). ![](https://europe1.discourse-cdn.com/flex013/uploads/make/original/3X/4/4/4454e6e01dfb86c97ce3423183eca64a605ae116.png) You can also select other old data to re-run your scenario with next using the “ **Choose manually** ” option. This will then show you a list of previous historical items you can select to process the next time the scenario is triggered. For more information, see - [Polling triggers](https://www.make.com/en/help/modules/types-of-modules#polling-triggers) - [Selecting the first bundle](https://www.make.com/en/help/modules/selecting-the-first-bundle) Hope this helps! Let me know if there are any further questions or issues. — @samliew * * * P.S.: Did you know, [the concepts](https://community.make.com/t/make-academy-course-overview/29699) of about 70% of questions asked on this forum are already covered in the [Make Academy](https://academy.make.com). Investing some effort into it will save you lots of time and frustration using Make later! ---
