omniauth-office365 gem permission error from Outlook rest API

Question

Hello All implementing basic office 365 integration to contacts from a rails application. I have already connected with google using omniauth-google-oauth2 and google-api-client. I am following https://docs.microsoft.com/en-us/outlook/rest/ruby-tutorial for app setup and am using the strategy omniauth-office365 as I did previously. It appears I have all setup right but when I authenticate I get the following error:

I have my settings in accordance to the docs, I dont know what I am missing..

The basic usage at this moment is just to authenticate which I have added the code below to omniauth.rb:

`

Rails.application.config.middleware.use OmniAuth::Builder do
     provider :office365, '$myid', '$mykey',
           {:scope => 'mail.read, User.read, profile,openid'}
end

I added a route to my routes.rb:

  get 'auth/:provider/callback', to: 'contacts#contact_integrations'

  get 'auth/failure', to: redirect('/')

In my controller I added:

  def contact_integrations
    access_token = request.env["omniauth.auth"]
  end

In a view I added a link to:

<%= link_to 'Outlook', "/auth/office365" %>

I did the above method with google and it worked fine, of course I added more code to get what I needed from the API but the upfront authentication was obtained. If I click the link I get the expected login/authenticate screens from office365, but it returns the permissions error shown in the image even though it is set to be able to access all accounts.

Answer 1

Issue was with the gem strategy omniauth-office365. I followed https://docs.microsoft.com/en-us/graph/tutorials/ruby?tutorial-step=3 and added that strategy and was able to authenticate..
