I am a newbie in the Rails ecosystem and stuck with configuring an existing Rails application to use ActiveStorage properly, unfortunately I cannot get information at this point from the developer, so I’m trying here to get some information about ActiveStorage and Rails to understand what the problem might be.
In one view, this function is used to return an Image URL
image_tag(card.image.variant(:large), alt: card.image.title)
results in in
which is not valid (1x1 pixel jpeg).
Another view uses
<%= image_tag image.variant(version), class: image_class(image), alt: image.title.unicode_normalize, title: image.title.unicode_normalize %>
and results in a valid URL with this URL components
<url>/rails/active_storage/representations/<somehash>/<anotherhash>--<shorthash>/<filename> (it’s the same file as in the other view).
Anyone has hints how I can troubleshoot this? Does ActiveStorage need additional configuration here in the production environment file?
