Conflict ActiveAdmin and Swaggard

Could someone guide me to find the solution?

The project was created with Rails 5 API.

The gem swaggard continues to function normally, but gem activeadmin is no longer working. The error that is happening is as follows:

Sprockets :: Rails :: Helper :: AssetNotFound at / admin / login The asset "active_admin.css" is not present in the asset pipeline

Here are also the gens I'm using in the project:
