I have my CalDAV set up and use it for several calendars.
However, I want to create a new Google Calendar for use with my husband. I created the calendar in Google. I do not remember how I created them. They show up in a tab called www.google.com (ie. NOT delegates). They all work and sync perfectly with all my devices.
Today, I created the new calendar and I followed added the calendar via delegate in the iCal preferences. Subsequently, I receive the following error:
There was an unexpected error with the request (domain (null) / error 0).
