Error when creating event in google calendar

[Benjamin]

Hello everyone,

I come again to ask for your help on the automation for integrating Airtable records into a Google Calendar. This automation only works when I duplicate my event in Airtable. I attach the capture of my automation. Do you have a trick to solve this problem?

Thank you so much.

To get the automation to run on records that already exist, you'll need to change the trigger.  My personal workaround is to add a checkbox field and just tick all the records I want the automation to run on

Good morning,
Thank you for your reply. Can you tell me the type of settings you make for the trigger and which script do you associate with the checkbox ?
Thank you so much.

Yeap here's a screenshot of the trigger:

Not sure what you mean when you say "which script do you associate with the checkbox", sorry
