Heroku Rails (No route matches [GET] "/")

I've had a Heroku app live for a few months-- checked on it today and it gave an error:

SyntaxError: Unexpected token < in JSON at position 0

The error in the Heroku logs is

ActionController::RoutingError (No route matches [GET] "/"):

Googling hasn't been illuminating, but I'm also confused as to why it stopped working so I'm not certain what to search for other than the error. All the endpoints are working fine. The routes look like this:

Rails.application.routes.draw do    get 'teams/index'    get 'players/index'    resources :players    resources :teams    resources :trades    resources :users    resources :votes    post '/login', to: 'auth#create'    get 'trades/index'    delete '/trades/:id', to: 'trades#destroy'  end  

What's missing?
