@andy.fingerhut Likely the code that detects the REPL type fails somewhere and tries to run some Lumo specific code.

Might be a good idea to file a ticket about this. Sadly I’ve had almost no time for inf-clojure in quite a while. There are still many low-hanging fruits there.

Thanks for the suggestion. Perhaps I will create an issue in case someone thinks of a possible root cause.

I’m 90% certain the issue is with of the call sites of https://github.com/clojure-emacs/inf-clojure/blob/master/inf-clojure.el#L309
