How to solve the [GET] “/login” routing error while building shopify app using ruby on rails?

Question

I am getting a Routing error says " no routes matches [GET] "/login" " and also in ruby libraries. During running on a server it displays page not found and the logs for that error is Logs show [GET] route error and library error .

I have my index file at following path

views/home/index.html.erb

My code in config/routes.rb is:

Rails.application.routes.draw do
root 'home#index' 
get 'show' => 'welcomes#show'
resources :home

I am working on this app for the last 10 days with the same route and ruby version without an error but now this error came from nowhere.

I am using heroku as my intermediate server.

Answer 1

There is no any route for /login in your config/routes.rb code. I guess you should define one.
