NuGet group repo with no proxy repositories gives UI error when PostgreSQL is used

Set up Nexus Repo 3.38.1 (orientdb install) with a NuGet group repository that does not contain any proxy repositories. I used this structure:

├ ⧈ nuget-group (nuget-group)
│   ├ • nuget-hosted1 (nuget-hosted)
│   └ ⧈ nuget-group2 (nuget-group)
│       ├ • nuget-hosted2 (nuget-hosted)
│       └ • nuget-hosted3 (nuget-hosted)

Shut down the instance. Migrate the database to PostgeSQL, and configure the instance to use the new database.

After restarting clicking on repository administration for any of the nuget group repositories will result in the error "Uncaught TypeError: Cannot read properties of undefined (reading 'proxy') (http://localhost:8081/static/rapture/nexus-coreui-plugin-prod.js?_v=3.38.1-01&_e=PRO:1)":

Expected: There is no proxy repository in this group. It looks like the code is assuming nuget group repositories always have at least one proxy repository? That's not a valid assumption.
