Nexus IQ for Azure DevOps not finding nupkg files

I have a .net core application for which I’m trying to add Sonatype scanning. I have the following task definition running on an ubuntu Azure DevOps build agent:

- task: NexusIqPipelineTask@1
              displayName: "Sonatype Lifecycle Scan"
                nexusIqService: 'myConnection'
                applicationId: 'myApplication'
                stage: 'Build'
                scanTargets: '/home/vsts/.nuget/packages/**/*.nupkg'

I’ve been able to validate that all the packages are, in fact, restored to /home/vsts/.nuget/packages prior to this task’s execution. The task result is:

Please advise on the correct syntax for the task to pick up .nupkg files.
