Error

The following was posted on github¹

Expected behavior

cider starts/operates without issue

Actual behavior

Upon trying to access a Clojure file after cider-jack-in, I cannot proceed past the following error.

Steps to reproduce the problem

1. cider-jack-in-clj
2. cider-load-buffer (`C-c C-k`)

Error:

cider-get-ns-name: Wrong number of arguments: ((clojure-mode-abbrev-table paredit-mode paredit-version paredit-space-for-delimiter-predicates font-lock-end font-lock-beg calculate-lisp-indent-last-sexp t) nil "Return the namespace of the current Clojure buffer.
Return the namespace closest to point and above it.  If there are
no namespaces above point, return the first one in the buffer.

Version: latest, but then tried to back-track and I’m still receiving it on CIDER 1.10.0 (Sant Cugat) #+end_src

Fix

I upgraded my Cider, then downgraded back to 1.10 stable. I also upgraded my cider-nrepl. Then I removed all calls to CLJ-Refactor, which tends to get in the way or cause problems. Then I finally upgraded a dependency I had totally forgotten about – clojure-mode, also maintained by the maker of Cider. After that the system was happy, and so was I!
