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
Also tried renaming the rabl file with and without .json — Saravanabalagi Ramachandran
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
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

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