Airbrake and Spree commerce API: undefined method `airbrake_request_data` - ruby-on-rails

Question

I use Airbrake to notify me about errors in my Spree Commerce shop. Now that I want to use the API of spree, I get the following error, when I try to post to http://localhost:3000/api/products to create a new product:
NoMethodError (undefined method `airbrake_request_data' for #<Spree::Api::V1::ProductsController:0x007f9fcdb81b58>):

Obviously, there is an error in my call. But I want to know which error. And of course, Airbrake should also notify errors from the API. I configured Airbrake with Spree so:
Gemfile
gem "airbrake"
initializers/airbrake.rb
Airbrake.configure do |config|
config.api_key = 'XXXXXXXXXXXXXXXXXXX'
end
So, a simple setup. I'm using Spree 1-2-stable, and I have no idea where to start to solve this problem.

You're encountering this error because the Spree API extends ActionController::Metal instead of ActionController::Base.
The airbrake gem performs some logic shown here:
https://github.com/airbrake/airbrake/blob/68543097a8731cf1f3e717946bd5ed33e5edccad/lib/airbrake/rails.rb#L13
which includes methods in to ActionController::Base.
You have a few options on how to get around this:
Load the methods in to ActionController::Metal as well using a similar method to that shown in the airbrake gem
Load the methods in to Spree::Api::BaseController using a similar method
Decorate Spree::Api::BaseController to include the methods directly
That should get you going.
