I got the following message when I updated my app to Rails 7.0.
DEPRECATION WARNING: image/jpg is not a valid content type, it should not be used when creating a blob, and support for it will be removed in Rails 7.1. If you want to keep supporting this content type past Rails 7.1, add it to `config.active_storage.variable_content_types`. Dismiss this warning by setting `config.active_storage.silence_invalid_content_types_warning = true`. (called from public_send at /Users/jnito/.rbenv/versions/3.1.0/lib/ruby/gems/3.1.0/gems/factory_bot-6.2.0/lib/factory_bot/attribute_assigner.rb:16)
