Spacemacs `An error occurred while installing copilot (error: (wrong-type-argument package-desc nil))`

Installing in spacemacs failed. Here is my .spacemacs sections:

  dotspacemacs-additional-packages '(
                                      (copilot :location (recipe
                                                          :fetcher github
                                                          :repo "copilot-emacs/copilot.el"
                                                          :files ("*.el")))
                                      )

I got the following error in *Messages*:

I updated my spacemacs (cd ~/.emacs; git pull) and the issue appeared to resolve
