Question regarding the product images uploading.

[imgarylai]

In our store, there are products without any variants. In this case, if I upload an image to these kinds of products. I got the error message.

The error message I got was

Module::DelegationError
signed_id delegated to attachment, but attachment is nil

Let me put a link to show the rest of the error message: https://sentry.io/share/issue/f09bf17e537a40768d0e25610acee431/

On the other hand, if a product has at least one variant, the image uploading works fine. However, mailchimp_image_url is still nil. It causes the image that doesn't properly show on the MailChimp.

And also is it possible to sync each of variant to Mailchimp as a single item? This might be another issue tho.

My workaround is by changing

spree_mailchimp_ecommerce/app/models/spree_mailchimp_ecommerce/spree/product_decorator.rb

Lines 24 to 28 in 79a5b2a

	def active_storage_url
	return "" unless images.any?
	Rails.application.routes.url_helpers.rails_blob_url(images.first&.attachment)
	end

to

def active_storage_url
  if images.any? && images.first&.attachment.attached?
    Rails.application.routes.url_helpers.rails_blob_url(images.first&.attachment)
  else
    ""
  end
end

Everything works fine, but I think there must be a better way to fix this.
