500 error when uploading a licence file

I tried to upload a licence file and admin/license/new produces a 500 error. Pasting the licence contents works ok. It seems to be GEO related. Using 8.5.5-rc.

NoMethodError (undefined method `split' for nil:NilClass):
  app/models/license.rb:49:in `license'
  app/models/license.rb:56:in `license?'
  app/models/license.rb:90:in `valid_license'
  app/controllers/admin/licenses_controller.rb:31:in `block in create'
  app/controllers/admin/licenses_controller.rb:30:in `create'
  lib/gitlab/middleware/readonly_geo.rb:22:in `call'

line 22 is just the middleware call:

        @app.call(env)

      def call(env)
        @env = env

        if disallowed_request? && Gitlab::Geo.secondary?
          Rails.logger.debug('Gitlab Geo: preventing possible non readonly operation')

          rack_flash.alert = 'You cannot do writing operations on a secondary Gitlab Geo instance'
          rack_session['flash'] = rack_flash.to_session_value

          return [301, { 'Location' => last_visited_url }, []]
        end

        @app.call(env)
      end

@axil should I close this issue?

Yeah, cannot reproduce in gdk.
