I'm trying to run boot repl and I get the following error.

I was following a guide on how to set up boot from spacemacs. The information there was outdated or wrong. The problem was that in my ~/.boot/profile.boot To solve the issue I had to change dependencies from what was on spacemacs site to what was on refactor-nrepl.

(require 'boot.repl)

(swap! boot.repl/*default-dependencies* conj
       '[refactor-nrepl "2.5.1"] 
       '[cider/cider-nrepl "0.25.9"])

(swap! boot.repl/*default-middleware* conj
       'refactor-nrepl.middleware/wrap-refactor)
