Rails 4 devise_invitable invitation token invalid - ruby-on-rails

Question

I have been following Ryan Boland's excellent Rails multitenancy tutorial, but have run into a snag with devise_invitable. I am using...
Rails 4.1.5
devise 3.3.0
devise_invitable 1.3.6
Postgresql
I create a new account and user/account owner on a chosen subdomain (mysubdomain.lvh.me:3000), from which I can send a user invitation just fine. I open the invitation link in an incognito Chrome session to ensure I am not logged in or have any current session. Upon clicking on the invitation link, I am redirected to the sign in page (mysubdomain.lvh.me:3000/users/sign_in) and see a flash notice: "The invitation token provided is not valid!"
I am using a very simple mailer view (app/views/devise/mailer/invitation_instructions.html.erb)...
<%= link_to 'Accept invitation', accept_invitation_url(#resource, :invitation_token => #token) %>
As you can see, I ensured the use of #token, as described here.
Upon creating the invitation, I have confirmed the invitation token is saved to the database (in this case for hey#test.com - d1801fd8df78bd8cd125d5d8091fdc6a72c8f8faf4136cb282d497ec612195e9). I have confirmed this matches the token on invitation lookup upon acceptance request (see below traces). Still, it redirects to user sign in page rather than completing sign up, and also displays in the trace log "Filter chain halted as :resource_from_invitation_token rendered or redirected". The user remains uncomfirmed in the end after this transaction.
Any ideas on what might be going wrong for me here? I am including logs, my application controller, and my devise config below...
Here is the trace log for the invitation creation:

Here is my Devise initializer (config/initializers/devise.rb), I have added the line "config.allow_insecure_token_lookup = true" to see if this helps, but to no avail...
Devise.setup do |config|
config.mailer_sender = 'please-change-me-at-config-initializers-devise#example.com'
require 'devise/orm/active_record'
config.case_insensitive_keys = [ :email ]
config.strip_whitespace_keys = [ :email ]
config.skip_session_storage = [:http_auth]
config.stretches = Rails.env.test? ? 1 : 10
config.reconfirmable = true
config.expire_all_remember_me_on_sign_out = true
config.password_length = 8..128
config.sign_out_via = :delete
config.allow_insecure_token_lookup = true
end

I'd prefer to comment but I have only 36 points and am not allowed so here's an incomplete answer:
this is the code from devise_invitable InvitationsController which is redirecting your request
def resource_from_invitation_token
unless params[:invitation_token] && self.resource = resource_class.find_by_invitation_token(params[:invitation_token], true)
set_flash_message(:alert, :invitation_token_invalid)
redirect_to after_sign_out_path_for(resource_name)
end
end
in your rails console try running:
token = '3GXDmi7NntDRdhvo57q5' #the token sent in the invitation email
User.find_by_invitation_token(token, true)
and see if that returns your User. It probably won't but maybe this will bring you closer to an answer. I hope so.
