I’m using n8n + Notion and running into an issue where the workflow creates duplicate pages unexpectedly.
I suspect the cause is that multiple updates happened within the same 1-minute polling interval, which caused the Notion Trigger to pick up the same data multiple times and execute the workflow more than once.
This issue does not occur when I manually run the workflow.
（That’s why I believe the problem is due to multiple trigger executions, not anything inside the workflow itself.）
Any advice on how to prevent this kind of duplicate execution from overlapping triggers?
