Starting Thunderbird 77.0b2 CalDAV calendar in Lightning no longer works. No events are loaded and in the console the error message below shows up several times:

Is there something I can do to fix this?

Try Beta three perhaps? Report a bug https://bugzilla.mozilla.org/home

Or if your not testing, perhaps just use the release version which is stable.

In the mean time it is beta 4 and the problem is till there. Though I guess the original post is rubbish and the reported error has nothing to do with the fact that Lightning + Davmail no longer work. But maybe the other error I get has something to do with CalDAV calendar not working:

TypeError: response.firstProps['D:supported-report-set'] is undefined CalDavCalendar.jsm:1521:13

I guess I will open a bug report than.
