Error when using :DeinUpdate

[Gordin]

I'm getting this error when I use :DeinUpdate

Error detected while processing function SpaceVim#commands#update_plugin[9]..SpaceVim#plugins#manager#update:
line   56:
E474: Invalid argument

I tried to look into the code in this repo to figure this out, but I don't know enough vimscript for this... When I press ENTER everything seems to work fine after that though.

I'm using nvim 0.5.0 Output of checkhealth:

In autoload/SpaceVim/plugin/manager.vim, there is a function SpaceVim#plugins#manager#update() in line187, the line 187+56=243, there is

call delete(repo.path, 'rf')

the variable repo comes from line 235:

let repo = dein#get(reponame)

the reponame comes from line 234

let reponame = s:LIST.shift(s:plugins)

when dein#get(reponame) is an empty dictionary which don't have the key 'path', will return an error. perhaps this is the origin of this error.
