[Cross-Post Spacemacs]

Hi, I have problems with my helm. In the past, I could resolve this by cleaning up the file history (M-x recentf-list-edit). But now, every time I try to open a folder in helm, I get this error message. (I turned on M-x edit-variables, debug-on-error t) Debugger entered--Lisp error: (wrong-type-argument arrayp nil) dired--make-directory-clickable() dired-readin() dired-internal-noselect("~/org/" nil) dired-noselect("~/org") run-hook-with-args-until-success(dired-noselect "~/org") #<subr find-file-noselect>("/home/kai/org/.") apply(#<subr find-file-noselect> "/home/kai/org/." nil) editorconfig--advice-find-file-noselect(#<subr find-file-noselect> "/home/kai/org/.") apply(editorconfig--advice-find-file-noselect #<subr find-file-noselect> "/home/kai/org/.") find-file-noselect("/home/kai/org/.") mapcar(find-file-noselect ("/home/kai/org/."))

You have a problem with the Spacemacs version of Helm, i.e. the one modified by Spacemacs. Helm itself doesn't suffer of this problem.

any ideas to tackle this?

No, you have to report this on Spacemacs. Don't know what their function calling helm-find-files does, and don't know what the advice they apply on find-file-noselect does (apparently it involves some dired stuff wrongly).

Maybe try turning off dired-make-directory-clickable (set it to nil) until Spacemacs fix the issue once reported.

I guess i fixed the issue. https://github.com/syl20bnr/spacemacs/issues/15808
