undefined method `invitation_created_at=' for #<User:0x007fd89b773c80>

I get undefined method `invitation_created_at=' for #User:0x007fd89b773c80 when I try to use User.invite!(:email => invitation_email). invitation_email comes from a form a user fills in to invite someone else.

I have not touched this rails app for a while but should just fix a couple of small issues and did a bundle update. Realised I didnt use the latest Devise and devinse_invitable but now has this in my Gemfile to use 1.2.2 and Device 3.1.0

gem 'devise', '>= 3.1'
gem 'devise_invitable', '>= 1.2', :git => 'https://github.com/scambra/devise_invitable'
´´´
Do not understand why this does not work? Do I need to do anything else when upgrading?

You must add invitation_created_at column, it was added on 1.2

Is this backward compatible with 'invitation_sent_at' from 1.1.x? I have an existing app and don't want to break existing invites when I deploy the upgrade to 1.2. Thanks!

If invitation_created_at is null, invitation_sent_at is used. Also, you can copy invitation_sent_at to invitation_created_at. If you don't use skip_invitation they should have same time
