If you are using Rails 6:

First go to your Gemfile and uncomment gem 'rack-cors'. Then run bundle install

After that go to config/initializers folder. There, you should find a file called cors.rb.

Uncomment the code that looks like this

Rails.application.config.middleware.insert_before 0, Rack::Cors do
  allow do
    origins 'example.com'

    resource '*',
      headers: :any,
      methods: [:get, :post, :put, :patch, :delete, :options, :head]
  end
end
Enter fullscreen mode Exit fullscreen mode

change the line that says origins 'example.com' to origin '*' or if you're request will be originating from a particular origin, then set it accordingly.

This worked for me. Hope it works for you as well. Cheers
