#35 Exception when syncing events with attachements

[The Lost One]

Syncing events with an attachement does not work.
I suppose that attachements are not supported but at least the events should be successfully synced with attachements omitted.

Here is a log:

The 400 bad request response from google has nothing to do with attachments, it is a more general problem when we sync updated events from outlook to google it seems. With SOGo it works, so I will investigate why Google doesnt't like the update.

Unfortunately there was an issue with WebExceptionLogging, which caused, that the response Body ( which usually contains a detailled error description) was not logged.
I fixed this issue a few minutes ago. Maybe this could be helpful, for your investigation.

Not much more info now:

Maybe the google-implementation doesn't accept updates without preconditions (with etag).

I added a branch ('feature/Update-With-Etag/' ), where the updates are done with preconditions.
Maybe this works with google.

still the same error.

Fixed with workaround to delete and recreate events instead of updating them for google
