500 Server Error shown in Chrome console when accessing Support Status page

I'm running a completely fresh instance of Nexus Repository Manager OSS 3.16.1-02 (installation via docker run).

When opening the developer console (F12) in Google Chrome and accessing the Server Status page (http://localhost:8081/#admin/support/status), this error is shown:

baseapp-prod.js?_v=3.16.1-02&_e=OSS:1 GET http://localhost:8081/service/metrics/healthcheck?_dc=1560239786678 500 (Server Error)

However, when checking the server logs, I see nothing related to any error....

Testing Notes

• The new health check endpoint that powers the system status page should only return a 200.
• If it returns anything else, the frontend will show some text warning the user that we couldn't get the system status information. (This should never happen)
• Only a user with the appropriate metrics permissions can see the system status page or use the new status/check REST API to view health check information.
