Crash on Edit link on the screen of Admin/team

In Admin/team screen, when I click on the Edit link, I got this error

Showing /home/david_ng_hk/.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/bundler/gems/administrate-66c6d333106b/app/views/fields/has_one/_form.html.erb where line #19raised:

uninitialized constant AvatarAttachmentDashboard

      
names.inject(Object) do |constant, name|
        if constant == Object
          constant.const_get(name)
        else
          candidate = constant.const_get(name)
          next candidate if constant.const_defined?(name, false)

Any one can help?

Confirmed here 👍 

If you remove `avatar_attachment` and `avatar_blob` from FORM_ATTRIBUTES in app/dashboards/team_dashboard.rb it works fine but of course then doesn't show any avatar fields on the Edit Team page.

FORM_ATTRIBUTES = [
    ...
    :users,
    :avatar_attachment, <= remove this line
    :avatar_blob, <= remove this line
    :name,
    ...

Are teams even supposed to have avatars? I have't looked into teams this much yet.
