Attached ICS Calendar does not create an event in the calendar

[Andre_LA]

Hello, everyone!

I created a template for ICS with the code below. The problem is that it sends the invitation to the ATTENDEES but does not create the invitation in the active user's calendar using the app.
The event is triggered by a change in a table record.
From the email attributes, I only fill the "To" field with a list of emails, excluding the email of the active user using the app.
In the invitation received by the ATTENDEES, the logged-in user's email appears as the organizer.
If I try to remove the ORGANIZER parameter or set the active user as an ATTENDEE, I get an error stating that it is not possible to modify the ORGANIZER.
I also tried fixing the ICS script without variables, and the problem remains the same.
In the monitor, the bot processes it normally.
Has anyone experienced this problem?
I wish you all a prosperous 2025.
Thank you very much for your help.

Here is the template:
