undefined method `cookie_value' for .... Impressionist gem

Question

I've set up the impressionist gem in my Film model. It has been working fine, updating the impressions count, but suddenly I've been receiving the following error when trying to GET the Films#Show page.

undefined method `cookie_value' for "60cb104e4befe185a8b81aac9a2c5e3c":String

It seems like it has something to do with the session_hash, but not sure how to solve this issue.

Does anyone have any ideas?

Here is my Film model:

    class Film < ApplicationRecord


  acts_as_votable
  is_impressionable

  mount_uploader :cover, ImageUploader
  mount_uploader :video, VideoUploader
  mount_uploader :trailer, VideoUploader



   def score
    self.get_upvotes.size - self.get_downvotes.size
  end

  extend FriendlyId
  friendly_id :title, use: :slugged

  # one film has many reviews
  has_many :reviews, dependent: :destroy

  validates :title, presence: true
  validates :author, presence: true
  validates :cover, presence: true
  validates :description, presence: true

end

Films show page

<%= render "shared/ticker" %>




<div class="back-to-films">
  <%= link_to films_path do %>
  <span><%= image_tag "BackArrow1.svg" %> </span><h3 class="back-to-gallery">Back to film gallery</h3>
  <% end %>
</div>



<section class="film-show-grid">

        <% end %>
        <span class="like_count">
          <%= @film.get_likes.size %>

  </span>

    <span class="views">
    <%= image_tag "view.svg", :class => "eyeball" %>
    <span class="impressions"><%= @film.impressionist_count(:filter=>:ip_address) %></span>
    </span>




    <div class="">
      <h2 class="film-title"><%= @film.title %></h2>
      <h6 class="film-author"><%= @film.author %></h6> <span><%= @film.description %></span>

I updated a legacy Rails application that is using the impression gem to version 6 and ran into the same exception. I worked around it by specifying a specific commit for the impression gem in the Gemfile:

gem 'impressionist',
  git: 'git@github.com:charlotte-ruby/impressionist.git',
  ref: '46a582ff8cd3496da64f174b30b91f9d97e86643'

The reason for this is that the fix for the exception is not in their latest release (2.0.0) but is in its master branch.

Jules, thank you very much! Your answer solved the issue. Just curious, how did you discover that this fix was in the master branch? – Aaron Z Dec 03 '20 at 19:08
I forked the gem to my local development environment and started debugging. When I couldn't reproduce the problem on `master`, I looked at the commit history of `app/controllers/impressionist_controller.rb` and found that the fix hasn't been released yet. – jules Dec 03 '20 at 19:24
Jules, have you had success deploying by specifying this commit in your gemfiile? I just tried deploying to Heroku, and on build, it's unable to access the Impressionist git - says 'host key verification failed - could not read from remote repository' – Aaron Z Feb 27 '21 at 18:23
@AaronZ I was able to deploy successfully to Heroku just now using the above snippet. While I don't have deploy issues, I'm looking to replace this gem to avoid issues in the future since this gem is no longer maintained. – jules Mar 02 '21 at 00:33
When I try to build for deployment, I receive errors in the build log: ```Fetching gem metadata from https://rubygems.org/............ Fetching git@github.com:charlotte-ruby/impressionist.git Host key verification failed. fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.``` You didn't have any of these errors? Did you git clone this gem & commit into your own local environment? Thanks for your info! – Aaron Z Mar 02 '21 at 10:07
@AaronZ - I've the same issue on deploy to heroku did you find the way to fix it? – nikos83 May 31 '21 at 10:14
@nikos83 I ended up cloning that particular impressionist file into a separate repo in my GitHub and used that one. This allowed me to bypass the access rights requirement. – Aaron Z Jun 01 '21 at 11:43
@AaronZ @nikos83 replace part `git: 'git@github.com:charlotte-ruby/impressionist.git',` with `git: 'https://github.com/charlotte-ruby/impressionist.git',`. this should help. – esherkunov Feb 15 '23 at 05:20
