Error when trying to retrieve events from Google Calendar

[nicholaskillin]

I have setup the Google Calendar Event integration and that seems to be working. I can get it to trigger automations based on events and if I click on the entity in my interface it shows me the next event on my calendar.

However I added this custom card and cannot get it to work. Right now I see the title of my calendar, so the JS seems to be in place and the custom card seems to be working, but I'm seeing errors in the console from when it tries to get events and I'm not sure how to fix it. Here is the error that I see.

I could very well have something setup wrong. Please let me know if you need more information.

Thanks!
