Adding the gem to the project changes the Content-Type of http response to my GraphQL API

[jivea]

Hello,
First of all, thank you for this very usefull and time saving gem.
Thanks to it, I could integrate MFA with Authenticar apps.

However, when deploying the feature to the testing environement, it appeared to break the JSON API of the project.
I could more or less isolate the problem that I can describe like this:

• Beside the usual web application, my Ruby on rails project runs an http API that inherits from ActionController::API.

• Simply adding the gem to the Gemfile changes the behaviour of this API: the Content-Type header of the response is set to 'text/plain' instead of 'application/json' and the returned data is empty. This causes api clients to break.

• If I comment the following lines of the gem, the Content-Type header is back to 'application/json', the data is OK and the API is fixed.
  lib/google-authenticator-rails/action_controller/rails_adapter.rb, lines 44 ->46

if defined?(ActionController::API)
ActionController::API.send(:include, GoogleAuthenticatorRails::ActionController::Integration)
end

I am pretty novice to Ruby on Rails and I have to admit that I don't understand much of what's going under all this.

Do you have an idea of how I could fix or workaround the problem ?

Hi @jaredonline, any thoughts on this topic?
What if I submit a pull request that adds a setting "Apply on API" ? Any chance to get it merged?

Heya @jivea sorry I've been slow to respond - I don't spend a lot of time on this project anymore.

I'm not really sure why adding the gem would change the response type of your API responses... I haven't encountered that before and there isn't anything in the project that should do that.

What version of Rails/Ruby/Bundler are you using? What other gems are in your gemfile?
