api_blueprint writer misses scope for scoped parameters

[sureshprasanna70]

The formatter used is api_blueprint. The generated docs misses the scope for parameters. Other writers like html, json and markdown works good. But api_blueprint misses the scope key This is my spec

resource "Invite",acceptance: true do
  

  route '/v1/invite/send',name: "Invite" do

    with_options :scope => :invitation, :required => true do
      parameter :first_name, "first name"
      parameter :last_name, "last name"
      parameter :email, "email"
    end


    post 'send invite' do

      context 'valid params' do

        example_request 'failed' do
          expect(status).to be(400)
        end

      end

    end

  end
end

Generated docs

@sureshprasanna70 can you post the rest of your example code so I can run it to track down the issue?

[sureshprasanna70]

@jakehow I'm sorry. This is the grape api

module Users
  class InviteAPI < Grape::API
    resources :invite do

      params do
        requires :invitation, type: Hash do
          requires :email, type: String, allow_blank: false, desc: "Invitee Email"
          requires :first_name, type: String, allow_blank: false, desc: "Invitee First Name"
          requires :last_name, type: String, allow_blank: true, desc: "Invitee Last Name"
        end
      end

      post "send" do
        authenticate_user!
        email = params[:invitation][:email]
        first_name = params[:invitation][:first_name]
        last_name = params[:invitation][:last_name]
        @invite = Invitation.new(:first_name => first_name,:last_name => last_name,:email => email,:user_id => current_user.id)
        if @invite.save
              return true
        else
            invitation_failed_error
        
         end
       end
      

    end

    helpers do
      def invitation_failed_error
        throw_errors(422, "Invitation failed")
      end

    end
  end
end

Hope this helps.

@sureshprasanna70 can you put the whole thing up as a repo or a gist? I don't use grape so don't know what the Gemfile should look like, etc. Looks like you have an Invitation model also.

I'm sorry and can't do that. The code is protected and can't be shared publicly. The invitation model contains the fields like first_name,last_name, email and user_id. The gemfile is
