ログを見てください。非推奨の警告があります:

DEPRECATION WARNING: Calling #default_scope without a block is deprecated. 
For example instead of `default_scope where(color: 'red')`, please use `default_scope { where(color: 'red') }`. 
(Alternatively you can just redefine self.default_scope.). (called from ...)

それを修正すると、例外が修正されます。
