I have been using Easy Appointment with the Extension for syncing with Google Calendar for over 6 months.  Today, the sync error log started creating the following entries and appointments are NOT being added to the Google Calendar. [2020-12-03 21:35:17.774877] [error] Error while sending Appointment #487 : Error calling POST https://www.googleapis.com/calendar/v3/calendars/stalc.org_n99ap8chhcqnik1mppca8ltdk0%40group.calendar.google.com/events: (400) The specified time range is empty. I have tried deleting my token and creating a brand new Credential on Google.  The Authentication works fine and I am granted access to calendar, but am getting this error.  I have also updated to the latest version of Easy Appointments and Extension.
