Why is my Rails site failing to push to Heroku? - ruby-on-rails

Question

I have a Rails site which previously deployed without a problem to Heroku. It worked fine until I added the following code to the production.rb file in order to make SendGrid work correctly.
Rails.application.configure do
ActionMailer::Base.smtp_settings = {
:address => 'smtp.sendgrid.net',
:port => '587',
:authentication => :plain,
:user_name => ENV['SENDGRID_USERNAME'],
:password => ENV['SENDGRID_PASSWORD'],
:domain => 'heroku.com',
:enable_starttls_auto => true
}
end
When I add this code the git push heroku master fails to push to Heroku.
However, the git push origin master works fine. What could possibly be going wrong?
Here is the build log from Heroku:
Rails.application.configure do
ActionMailer::Base.smtp_settings = {
:address => 'smtp.sendgrid.net',
:port => '587',
:authentication => :plain,
:user_name => ENV['SENDGRID_USERNAME'],
:password => ENV['SENDGRID_PASSWORD'],
:domain => 'heroku.com',
:enable_starttls_auto => true
}
end
