End of file (EOF) error when delivering an email using Mail_Form gem

I have a simple form set up for a contact object

<%= simple_form_for @contact do |f| %><%= f.input :name %><%= f.input :email %><%= f.input :message %><%= f.button :submit %><% end %>

class Contact < MailForm::Base    attribute :name, validate: true    attribute :email, validate: true    attribute :message      def headers      {         subject: "My Contact Form",        to: '#####gmail.com',        from: %("#{name}" <#{email}>)      }    end  end

the object is created as expected but upon sending the mail in the contact controller using .deliver

class ContactsController < ApplicationController    def create      @contact = Contact.new()      @contact.name = [:name]      @contact.email = [:email]      @contact.message = [:message]      if @contact.deliver        render json: {message: "Email sent successfully"}      else        render json: @contact.errors      end    end  end

I get the following error - EOFError in ContactsController#create

When I have tried to call .deliver on a contact object within IRB it provides me with the following

my smtp setup in development.rb is as follows

 config.action_mailer.perform_deliveries = true  config.action_mailer.default_url_options = { host: 'localhost:3000' }  config.action_mailer.raise_delivery_errors = true  config.action_mailer.delivery_method = :smtp  config.action_mailer.smtp_settings = {  address: 'smtp-relay.gmail.com',  port: 587,  domain: '@gmail.com',  authentication: 'plain',  enable_starttls_auto: true,  user_name: ENV['username'],  password: ENV['password']

I appreciate this is a lot of code to dump on here but I am really at my wits end with this problem. If anyone needs any further information to help please let me know.

So far I have tried looking into the EOF error but have really had limited luck as the error message is quite brief. I have treid changing the port as well as the local host address but nothing seems to work.

The parameters on the error page are as follows

{"authenticity_token"=>"[FILTERED]", "contact"=>{"name"=>"fff", "email"=>"ffff", "message"=>"fffff"}, "commit"=>"Create Contact"}
