Automation triggered twice with Google Calendar pack

Hi, I’m using Coda to plan tasks and manage roadmaps for our team.

I’m displaying a “master” task list in a Gantt view.

I also sync a calendar using the Google Calendar pack into a events table. This one I display in the calendar view.

I thought it would be nice to have the calendar events also displayed in the Gantt view and I want to add them from events to task list using automations.

However, using “When: row changed” and “Then: add or modify row”, a new event in Google Calendar is added twice to task list.

Any idea on how to fix that?

Is this happening for every response or only the first response?
