WebApp Error: <class 'kallithea.lib.vcs.exceptions.NodeError'>: Only DirNode and its subclasses may be initialized with empty path

[Tim Downey]

Hi folks,

I'm in the process of migrating my Rhodecode over to Kallithea.  I've set
up the new Kallithea system and cloned my repos, but haven't yet cut my
users over.  I got this error message a few times over the weekend, but
it's not clear to me what it means.

It's possible that it has been happening all along on my Rhodecode server,
but I wouldn't have known since I apparently didn't have email configured
properly.

Can anyone shed light on this?  See below for the full error:
