Heroku/Devise throwing this error: ActionView::Template::Error (Invalid :protocol option: 0):

When I try to use email features of my otherwise successfully deployed Rails 4 application, I get this error: 

ActionView::Template::Error (Invalid :protocol option: 0):

Here is the log of that request: 

app[web.1]: Started POST "/users" for 000.000.000.00 at 2014-08-14 21:37:43 +0000

app[web.1]: 
app[web.1]: 
app[web.1]: Completed 500 Internal Server Error in 723ms

This is in my environment.rb

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
}

This is in my production.rb:

config.action_mailer.raise_delivery_errors = false
config.action_mailer.perform_deliveries = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { host: :'myapp-staging.herokuapp.com' }
config.action_mailer.default :charset => "utf-8"

As you can see, I'm using the SendGrid addon. Has anyone seen this error and could you point me toward a potential solution?

I figured it out. I'd entered an errant semi colon. The value of config.action_mailer.default_url_options in production.rb should read thusly:

config.action_mailer.default_url_options = { host: 'helloworkout-staging.herokuapp.com' }
