Caddy not rendering assets - ruby-on-rails

Question

I have a rails application that is not rendering assets. It was previously working fine. When I added linked files it not only uploaded the files I specified but also precompiled assets. Even after clobbering all assets and recompiling it fails to render them even though that exist on the box.

I was able to get this working but using the fileserver directive.
https://example.com {
encode zstd gzip
root * /home/deploy/apps/rails-app/current/public
file_server
tls user#email.com
#notStatic {
not file
}
reverse_proxy #notStatic unix//home/deploy/apps/rails-app/shared/tmp/sockets/rails-app-puma.sock
header / {
Strict-Transport-Security "max-age=31536000"
}
}
