Rails 5 Filter chain halted as :set_product rendered or redirected error when indexing all products

I'm running a Rails api-only app with a product model. I've created products on the backend with activeadmin. When using postman to view individual products with a corresponding product ID, it returns the json data fine but when I try to view all product at: api/v1/products

I get this error:

Started GET "/api/v1/products/" for ::1 at 2019-05-28 11:12:47 +0100Processing by Api::V1::ProductsController#index as JSONParameters: {"product"=>{}}Filter chain halted as :set_product rendered or redirectedCompleted 404 Not Found in 5ms (Views: 0.2ms | ActiveRecord: 4.9ms)

Here's my controller:

module Api  module V1    class ProductsController < Api::V1::ApiController      # do not authenticate users before viewing product listing or individual products      before_action :authenticate_user!, except: %i[index show]      before_action :set_product, only: %i[index show]      # GET /product      def index        product = Product.all.order('id')        render json: { success: true, data: product }, status: :ok      end      # GET /products/:id      def show        @product = Product.find(params[:id])        render json: { success: true, data: @products }, status: :ok      end      private      def set_product        @products = Product.find(params[:id])        rescue StandardError => error        render json: { success: false, error: error }, status: 404      end      def product_params        params.require(:product).permit(:title, :release_date, :release_time, :description, :price, :brand)      end    end  endend

Here are my API views:

_product.json.jbuilder

json.id               product.idjson.title            product.titlejson.description      product.descriptionjson.release_date     product.release_datejson.release_time     product.release_timejson.price            product.pricejson.brand            product.brand

index.json.jbuilder

json.array! @products, partial: 'products/product', as: :product

show.json.jbuilder

json.product do  json.partial! 'product'end

routes

namespace :api do    namespace :v1, defaults: { format: :json } do      devise_scope :user do        get :status, to: 'api#status'        resource :user, only: %i[update show] do          get :profile        end      end      resources :products, only: [:index, :show]    end  end
