Rails api-only ignoring rabl files

Question

I have what I believe to be a very simple app, with Rails 5 (API only) but for some reason it is returning an empty response while it should be returning a json object (using RABL)

class ExercisesController < ApplicationController
  before_action :set_exercise, only: [:show, :update, :destroy]

  def index
    @exercises = Exercise.all

    # Works
    # render json: @exercises

    # Blank response
    render :index
  end
end

# app/views/exercises/index.json.rabl
collection @exercises
attributes :id, :name

If I use a direct render (commented) it works properly, but with the rabl template it is blank... any thoughts?

in fact, it returns blank for **whatever** is typed after `render` (though statuses are processed perfectly). Tried `render 'exercises/index'`, `render 'index'`. — Saravanabalagi Ramachandran, Nov 25 '16 at 11:06
Also tried renaming the `rabl` file with and without `.json` — Saravanabalagi Ramachandran, Nov 25 '16 at 11:09
Is there any other view registered for that action, e.g. `index.html.erb`? What is the output of `render text: @excercies.inspect` ? — phil pirozhkov, Nov 25 '16 at 15:37
I think the issue is also related to the libraries loaded. Have you loaded Rabl? Because the `--api` flag limits the amount of libraries that Rails loads, and may not have rendering setup in such a way that Rabl hooks into it properly. — ekampp, Mar 31 '17 at 23:10

Try adding config.view_paths = ['/app/views'] to your configuration.
