Turbo not streaming changes properly / window.Turbo is undefined

[TaylorJonesTRT]

To begin I'm not sure if this is a turbo-rails 2.x.x issue or all around.

Whenever I attempt to have my rails app render a turbo_stream.replace, the browser instead of rendering the replacement is downloading the raw html file of the actual turbo_stream replacement.

I'm using old code from a few months back from when this was originally working (my gemfile.lock says I was on 1.5.0) back then with a new Rails app that was just scaffold-ed.

When attempting to dive into this and figure out the issue I did find out that window.Turbo is undefined in my console on the Rails app.

My controller code:

    exercise_name = exercise_params[:name]

    @exercise = Exercise.build(name: exercise_name, user_id: current_user.id)

    if @exercise.save
      update_exercise_list
    else
      render exercises_path, status: :unprocessable_entity
    end
  end

  private

  def exercise_params
    params.require(:exercise).permit(:name, :personal_best)
  end

  def update_exercise_list
    render turbo_stream: turbo_stream.replace('exercise_list',
                                              partial: 'exercises/exercise_list',
                                              locals: { exercises: current_user.exercises.order(name: :asc) })
  end

My partial view that contains the turbo frame:

  <ul class="mt-5">
    <% exercises.each do |exercise| %>
      <li>
        <%= exercise.name %>
      </li>
    <% end %>
  </ul>
<% end %>

The attached files are what my browser downloads exercises.txt exercises(15).txt

This still works properly in my old project but does not when I force my current project to use 1.5.0. In chrome it doesn't download a file but displays the raw html as text.

I have to do some back tracking but I was able to resolve this issue, don't believe it's anything in the package/gem itself.
