Nexus 3.74.0 Nuget (hosted) Feed Cleanup Policies does not cleanup V3 registration page

[oed-pelza]

• What problem are you trying to solve?
  we are working with nexus repository 3.74.0 and having several nuget v3 (hosted) repositories. We enabled the cleanup policies for some test repositories and want to delete assets which are older than 10 days.

We hosting chocolatey packages on these feeds and when chocolatey is downloading a asset, its creating a /v3/registration//index.json.

Microsoft decscribes that as the “registration page” for nuget v3 specification:
Package Metadata, NuGet API | Microsoft Learn

When you deleting a asset from the nexus webgui or api, the registration page/index.json is automatically deleting too.

When you using the cleanup policy, it will delete the asset but not the index.

You can see the issue in this video:

• Do you have a workaround you are using at present?
  The workaround is a script which is deleting from the api.

• What feature or behavior is this required for?
  The cleanup policies should have the same behavior when you deleting from the webgui or the api.

• Tell us about your Nexus Repository deployment: what version, operating system, and database are you using?
  Windows Server 2022
  Nexus Repository OSS 3.74
  H2 Database
