I deployed a instance manually on a centos host, image upload does not work, after several hours of debug, I find file in Scheduler::Defer block lost some attribites, see debug code below

```
def create
    type = params.require(:type)
    file = params[:file] || params[:files].try(:first)
    url = params[:url]
    client_id = params[:client_id]
    synchronous = is_api? && params[:synchronous]

    if type == "avatar"
      if SiteSetting.sso_overrides_avatar || !SiteSetting.allow_uploaded_avatars
        return render json: failed_json, status: 422
      end
    end

    Rails.logger.error(file.tempfile.path) # =>url

    if true #synchronous
      data = create_upload(type, file, url)
      render json: data.as_json
    else
      Scheduler::Defer.later("Create Upload") do
        Rails.logger.error(file.tempfile.path) # => nil
        data = create_upload(type, file, url)
        MessageBus.publish("/uploads/#{type}", data.as_json, client_ids: [client_id])
      end
      render json: success_json
    end
  end

```

any one know what’s going on here?
