I am getting a mystifying error when trying to access Questions#Show. Anytime I redirect to the View, I get a 500 internal server error. According to my server trace, the issue is in the Questions controller in 'set_question'
Started GET "/questions/1" for 127.0.0.1 at 2020-02-01 18:57:34 +0100
Processing by QuestionsController#show as HTML
Parameters: {"id"=>"1"}
User Load (1.1ms) SELECT `users`.* FROM `users` WHERE `users`.`id` = 1 ORDER BY `users`.`id` ASC LIMIT 1
Question Load (3.5ms) SELECT `questions`.* FROM `questions` WHERE `questions`.`id` = 1 LIMIT 1
↳ app/controllers/questions_controller.rb:105:in `set_question'
Completed 500 Internal Server Error in 15ms (ActiveRecord: 4.6ms | Allocations: 3861)
TypeError - can't quote Rack::Session::SessionId:
However I am not quite sure what is wrong with it

Anyone familiar with this TypeError? I have tried Google and StackOverflow and haven't seen any hints I have used virtually identical code for other models, however this is the only one which gives me a TypeError

Apparently, there is nothing wrong with your set_question method. The error says: TypeError - can't quote Rack::Session::SessionId: and that is happening in impressionist :actions => [:show], unique: [:session_hash].
I haven't used this gem so can't exactly tell you how to counter that error but to prove my point, if you comment this line (line 3) in your controller, it will work.
You need to read more about implementing this gem to resolve it.
