Marksmith exception on 3.23.0

[themire]

Our CI is breaking on 3.23.0 with this error

The asset "marksmith.css" is not present in the asset pipeline.

We use it for markdown fields. We just include the gem in our gemfile and also have the following initizlier

Marksmith.configure do |config|
  config.automatically_mount_engine = false
end

Is there anything we're missing to get this CSS included?

AVO-720 Marksmith exception on 3.23.0

Hi @themire

We're using Avo 3.23.0 alongside Marksmith 0.4.6 and it's working fine on our demo app: https://main.avodemo.com/avo/resources/projects/37/edit

I assume it's something related to your application or configuration. Let's try to figure it out together.

What version of Marksmith are you using?

[themire]

We're on 0.4.5. These are all the references we have to marksmith. I'll try upgrade it to see if it helps. Thanks!

[Paul-Bob]

Could you try reverting config.automatically_mount_engine = false to true and comment out the manual mounting point in your routes?

[themire]

Hmm. Upgraded marksmith, removed the initalizer and the route. Still getting the error. On Ruby 3.4.5.

I've tried reproducing this in several apps without any issues. It's working fine on all of them. I see you're using Sprockets. I've tested with both Sprockets and Propshaft and it works as expected.

I'd start by searching for config.assets and see if there's any app setting that could be causing this error.
