I'm experiencing issues with negative captcha, but it doesn't occur everytime, and I still can't figure out a pattern out of it.

Here's the stacktrace:

It only occurs in production which is the most annoying of course.

So the error comes from this file _suggest_cospace_modal where negative_captcha(@suggest_cospace_captcha) is executed, and apparently @suggest_cospace_captcha can be nil.

And here's how @suggest_cospace_captcha is initialized, in application_controller.rb

before_filter :suggest_cospace_captcha

  def suggest_cospace_captcha()
    @suggest_cospace_captcha = NegativeCaptcha.new(
      secret: NEGATIVE_CAPTCHA_SECRET,
      spinner: request.remote_ip, 
      # Whatever fields are in your form
      fields: [:name, :country, :city, :name_of_contact, :mail_of_contact, :website_url, :comment],  
      params: params
    )
  end

I found only this issue related: #7

But it could not help unfortunately.

Thanks for support, this gem is really good and negative captcha is a really smart feature to have!
