Heroku Mailer Delayed Job failed with ArgumentError: wrong number of arguments (0 for 1) - 0 failed attempts



I have created two mailers, one of which is not working in production on Heroku. The other mailer has been tested and it works, so I know the email configuration with sendgrid is working.


I have an invitations model:


class Invitation < ActiveRecord::Base
attr_accessible :recipient_email, :sender_id, :sent_at, :token
belongs_to :sender, :class_name => 'User'
has_one :recipient, :class_name => 'User'
validates_presence_of :recipient_email
validate :recipient_is_not_registered
validate :sender_has_invitations, :if => :sender
before_create :generate_token
before_create
