Getting "undefined method `flash`" for my controllers after updating Rails from 4.1 to 5.2 and added the responders gem

Question

I'm in the process of updating rails from 4.1 to 5.2 I added the responders gem so respond_with is present. My ApplicationController now looks like this:

class ApplicationController < ActionController::API self.responder = ApplicationResponder respond_to :html

However, when I call respond_with I get this error:

 NoMethodError: undefined method `flash' for #<MyController>

I noticed in the responders README that there is a flash responder, however I do not want to use that.

Adding this method to the controller fixed the issue `def flash {} end` — Im_Matt_Murdock, Dec 04 '18 at 19:52
The above gets the code to run, but I cannot render html now, only json — Im_Matt_Murdock, Dec 05 '18 at 23:15
