Internal error after accidently downgrading sapling

I accidentally downgraded sapling from some HEAD build to the current release in homebrew (2020.02.19), and am hitting this internal error (below). No expectation of backwards compatability, but a more explicit error message would be helpful. Also, could you put a new build on homebrew?
$ sl goto remote/master
