Not working in Rails 6.1.4.1, "The asset "logs/application.css" is not present...

[listenlight]

Will not work in Rails 6.1.4.1. Here is the trace. I'm confused. Most mount plugins use at: '/logs' instead of => /logs`. Can you help me?

method=GET path=/logs/ format=HTML controller=Logs::LogsController action=index status=0 error='ActionView::Template::Error: The asset "logs/application.css" is not present in the asset pipeline.
' duration=21 view=0 db=0 time=08/21/21 10:26:52 resource=logs/logs#index

@listenlight I know it's over 2 years later now, and Rails is on 7, but I was able to fix this by adding two lines to the bottom of app/assets/config/manifest.js and restarting the server:

...
//= link logs/application.css
//= link logs/application.js
