Trying to Parse and Display Image Using Feedjira Gem

I'm trying to display an image using the Feedjira gem for an RSS reader that I'm working on.

I created the method in the model:

Feed.rb

def self.feed_image(url)
    Feedjira::Feed.add_common_feed_element 'img'
    image = Feedjira::Feed.fetch_and_parse url
end

I'm trying to display it in the show page so I call it in the controller:

feeds_controller.rb

 def show
    @feed = Feed.find(params[:id])
    @title = @feed.feed_title
    @entries = @feed.entries
    @feed_image = Feed.feed_image(params[:id]) <-----
 end

I added the params in order to pull the url that is calling the feed on the show page. I try to display it in the view as follows:

show.html.erb

<h3><%= @feed.url %></h3>
<%= image_tag @feed_image %>  <---------
<% @entries.each do |t| %>
  <%= link_to t.title, t.url %></br>
  <small><%= t.published %></small>
  <%= sanitize t.summary %>
<% end %>

I'm getting the following error when I try to call it:

NoMethodError (undefined method `request_uri' for #<URI::Generic /1>):
  app/models/feed.rb:19:in `feed_image'
  app/controllers/feeds_controller.rb:12:in `show'

I'm not sure if it's not reading the URL correctly or where exactly I went wrong. Anyone have any idea where I went wrong.
