You can avoid this using the `stale_when_importmap_changes` method:
 
 ```ruby
 class ApplicationController < ActionController::Base
-  etag { Rails.application.importmap.digest(resolver: helpers) if request.format&.html? }
+  stale_when_importmap_changes
 end
 ```
 
+This will add the digest of the importmap to the etag calculation when the request format is HTML.
