dotspacemacs/user-config: Wrong number of arguments: #<subr persist--defvar-1>, 2

[vitaminace33]

After a recent update (spacemacs and packages), I get the following error at startup.

dotspacemacs/user-config: Wrong number of arguments: #<subr persist--defvar-1>, 2

Commenting the line

(require 'org-gcal)

"solves" the issue... Before such line, I have previously defined org-gcal-client-id, org-gcal-client-secret, and org-gcal-fetch-file-alist.

Spacemacs doesn't have any support or configuration for that package so you should probably report this issue upstream to that package's maintainer. emacs --debug-init's output will likely be useful for that report.
