Rails 5.2.0 images.attach results in InvalidSignature error - rails-activestorage

Question

I am upgrading to Rails 5.2.0 and attempting to use ActiveStorage to save images from a data feed. In development.rb I have config.active_storage.service = :local and the model has has_many_attached :images and storage.yml has the default :local settings and the controller action has
def listing_params
params.require(:listing).permit(:beds, :baths, :price, :parking, :description, :active, :prop_type, :latitude, :longitude, :address, :city, :city_id, :state, :state_id, :zip, :lo_name, :la_fname, :la_lname, :la_phone, :la_email, :mlsid, :cp, :st_number, :st_suffix, :baths_full, :baths_half, :status, :modtime, :st_name, :featured, :school_id, :picture_count, :parking_type, images: [])
end
My code is getting hung up on this line
listing.images.attach(pics) with this error: ActiveSupport::MessageVerifier::InvalidSignature: ActiveSupport::MessageVerifier::InvalidSignature
My code:
def perform
require 'aws-sdk-s3'
require 'rets'
client = Rets::Client.new({
login_url: LOGIN_URL,
username: LOGIN,
password: PASSWORD,
version: VERSION
})
begin
client.login
rescue => e
puts 'Error: ' + e.message
exit!
end
p "Logged in"
Listing.find_each do |listing|
mlsid = listing.mlsid
photos = client.objects '*', {
resource: 'Property',
object_type: 'Photo',
resource_id: mlsid
}
p "about to attempt to attach #{photos.count} images to listing#{listing.id}"
pics = []
photos.each do |data|
pics << data.body
end
listing.images.attach(pics)
puts "#{photos.count} images attached to listing##{listing.id}"
end
end
And the full error after running with --trace:
tomb$ rake update:listing_images --trace
** Invoke update:listing_images (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute update:listing_images
Cookie#domain returns dot-less domain name now. Use Cookie#dot_domain if you need "." at the beginning.

You’re passing an array of Rets::Parser::Multipart::Part objects to ActiveStorage::Attached::Many#attach. It doesn’t know how to handle them.
For each photo, call #attach with an IO and a filename:
photos.each_with_index do |photo, index|
listing.images.attach(io: StringIO.new(photo.body), filename: "photo-#{index + 1}.png")
end
