NoMethodError (undefined method `id' for {"init"=>true}:Hash):

[GraemeHarrison]

I keep getting this error:

NoMethodError (undefined method `id' for {"init"=>true}:Hash):

For my setup, I added is_impressionable to my Posts model, and in the PostsController I am testing with a simple method like so:

def mark_as_viewed
    impressionist(@post)
end

I can think of a few places where things may have gone wrong to cause the error. The first is that I changed all the id types in the gem's migration to use UUIDs. The result is this:

class CreateImpressionsTable < ActiveRecord::Migration[6.0]
  def self.up
    create_table :impressions, id: :uuid, :force => true do |t|
      t.string :impressionable_type
      t.uuid :impressionable_id
      t.uuid :user_id
      t.string :controller_name
      t.string :action_name
      t.string :view_name
      t.string :request_hash
      t.string :ip_address
      t.string :session_hash
      t.text :message
      t.text :referrer
      t.text :params
      t.timestamps
    end
    add_index :impressions, [:impressionable_type, :message, :impressionable_id], :name => "impressionable_type_message_index", :unique => false, :length => {:message => 255 }
    add_index :impressions, [:impressionable_type, :impressionable_id, :request_hash], :name => "poly_request_index", :unique => false
    add_index :impressions, [:impressionable_type, :impressionable_id, :ip_address], :name => "poly_ip_index", :unique => false
    add_index :impressions, [:impressionable_type, :impressionable_id, :session_hash], :name => "poly_session_index", :unique => false
    add_index :impressions, [:controller_name,:action_name,:request_hash], :name => "controlleraction_request_index", :unique => false
    add_index :impressions, [:controller_name,:action_name,:ip_address], :name => "controlleraction_ip_index", :unique => false
    add_index :impressions, [:controller_name,:action_name,:session_hash], :name => "controlleraction_session_index", :unique => false
    add_index :impressions, [:impressionable_type, :impressionable_id, :params], :name => "poly_params_request_index", :unique => false, :length => {:params => 255 }
    add_index :impressions, :user_id
  end

  def self.down
    drop_table :impressions
  end
end

The second is that when I initially installed the gem I was seeing a different error that said something like

undefined method `cookie_value' 

which I got around by installing a specific commit, as suggested in this post.

Here's a stack trace of the issue:

I have made sure that params[:id] is correct, @post is set correctly, and that current_user is set correctly, so I'm not sure what's causing this issue.
