Appsheet sync failing to push to Calendar

[MKapfer]

I have an App I'm working on, and the goal is to have the user input some data and thus creating a calendar event for that form. I have a weird error/bug/user error happening, I input the needed information, then when i go select my action i created to "push to calendar" it immediately appears in the appsheet calendar view with the sync indicating 1 item is syncing, that 1 item never syncs and so it doesn't appear on my actual google calendar. If I refresh the browser or re select the sync button, I get this error ' Unable to add row to table 'CSR Calendar'. → Invalid attendee email. [it gives me this error 3 times, not sure if that's useful information or not]

In the field for email, i entered my appsheet account email, so I know its a valid email address. 

This is my first time trying to integrate Calendar and Appsheet so I could be missing a fundamental feature or concept about how they work together or cant work together.
The calendar is created by my same account to use appsheet, I have double checked the permissions in the calendar. I have the Calendar added as a Data Source.

I think I found it, I had Attendees set wrong. Needed to be set to an email field not the Employees[_ComputedName]
