Validation error - {"template-content": "please enter an array", "message": "please enter an array"}

[David]

I'm trying to send out transactional emails using Mandrill on Rails 3.2.8 (using this gem: https://github.com/tatemae-consultancy/mandrill).

Here is the code to send the mailer:

def mail_out

  m = Mandrill::API.new(ENV['MANDRILL_PASSWORD'])

  content = [ { "name": "blah", "content": "blahblah"} ]

  mailing_list = [ {'email': 'em...@mail.com'}, {'email': 'em...@mail.com'}, {'email': 'em...@mail.com'} ]

  m.messages 'send-template', {

    :key => ENV['MANDRILL_PASSWORD],

    :template_name => 'Name of template under outbound -> templates'

    :template_content = content

    :message => {

      :subject => 'Subject of email',

      :from_email => 'mye...@email.com',

      :from_name => 'name',

      :to => mailing_list

    },

    :track_opens => true,

    :track_clicks => true

  }

end

I call a rake task to send this:

task :mail => :environment do

  MyClass.mail_out

end

I get this error:

(-2) Validation error: {"template-content": "please enter an array", "message": "please enter an array"}

When I dump out the message to send in the console, I can correctly see that "template_content" and "message" are passing an array of hashes.  Any ideas as to why this is happening?

Hi David,

Sorry for the delay in a response here.  I think we got you taken care of via email, but I thought I'd respond in case others are having the same issue.

The error message seems to be being generated by the specific API client being used, and not the Mandrill API.  There's an outstanding pull request that seems to address this issue:
