Google calendar sync issue (Request parameter validation failed)

Now when I start the eM client (4.0.15145) i always get this error

08:58:08 MailExceptions.OperationException: Uploading events to calender ‘[MAIL]/[MAIL]/’ failed with an error: Request parameter validation failed for [Google.Apis.Requests.Request(instances @ https://www.googleapis.com/calendar/v…)] —> System.InvalidOperationException: Request parameter validation failed for [Google.Apis.Requests.Request(instances @ https://www.googleapis.com/calendar/v…)]

I have looked in my calendar and I don’t have any appointment at 2011-11-15 8 AM, neither on google’s server nor in em client.

But the calendar synchronization still seem to work, all events seem to sync correctly.

Try this version: http://www.emclient.com/dist/v4.0.153…

EM at the moment is using Google Calendar’s native API instead of CalDAV, which is a bit unstable at the moment (Google-side), if it still not working, create a GData log and request a support ticket to send it.

I tried the even newer 5.0.15488 and still got the same error…

I would suggest you to create a log for Gdata and request support to send the log.

To create the log, at the menu -> Settings -> Logging.

I did that and sent it to the support mail
