ProGet shows "(500) Server Error: Value cannot be null. (Parameter 'version')" when opening "Dependencies" tab of Maven artifact

Hi,

I run a local ProGet installation (5.3.29 (Build 19)) with a Maven feed. When I click on the "Dependencies" button in the artifact's detail view of a deployed Maven artifact in the web UI, I get the following error page if the artifact uses Spring Boot:

In ProGet's logs, the following error message is logged:

An error occurred in the web application: Value cannot be null. (Parameter 'version')

with stack trace:

I guess that this error may be caused by the (intentionally) missing version element in the project's pom.xml because its dependency versions are managed by the parent pom's dependencyManagement section (e.g. of Spring Boot).

Is there a way that ProGet can cope with "parent-managed" dependency versions in future or, at least, does not throw this error?

For sure! It does look like this is supported in most places, but not on this page in the UI.

Easy fix... I logged this as PG-1968, and it will ship in the next maintenance release of ProGet, which is scheduled for next Friday. Or I can show you how to download a pre-release if you'd prefer sooner :)

@atripp Thank you very much! I upgraded to ProGet version 5.3.32 (Build 11) and the error is gone.
