File upload does not work with Rails 4 in development using Pow and Nginx

Question

I use Pow and Nginx to service my Rails 4 application in development. A simple file download returns 500 errors, and the request does not reach the Rails controller. I assume this is because the request is not mentioned in the Rails log. Without mentioning the error, I'm not sure what is going wrong here.

I started by loading the Ajax file, but replaced it with a simple form that also doesn't work.

Tried this

and then moved on to this

Current avatar .html.erb

<%= form_for @user, html: { multipart: true }, method: "post", url: '/settings/avatar/update', class: "", id: "update_avatar" do |f| %>
  <%= f.file_field :avatar, class: 'js-upload-photo-button js-change-avatar-btn', accept: 'image/png,image/gif,image/jpeg,image/jpg' %>
    <%= f.submit "Upload" %>
<% end %>
