Description
Receiving a general error when trying to launch or open configuration manager:
System.ArgumentNullException: Value cannot be null.Parameter name: keyat System.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)at System.Collections.Generic.Dictionary`2.FindEntry(TKey key)at System.Collections.Generic.Dictionary`2.TryGetValue(TKey key, TValue& value)at Quest.Reporter.Consoles.Discovery.LicenseCheckHelper.UserIsCompliant(HashSet`1 usedDiscoveryTypes)at Quest.Reporter.Consoles.Discovery.ReporterShell.PerformLicenceCheck()at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem()at System.Threading.ThreadPoolWorkQueue.Dispatch()at System.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)After closing the above error the console crashes and closes automatically. -
Cause
This issue could be due to a discovery not having a discovery type.
-
Resolution
WORKAROUND:
Normally, in the Manage Discovery screen you see all your discoveries and in the Type column is seen the type such as Active Directory, Computer, NTFS, and other types, but if you see a Discovery with an empty or blank discovery type as seen above, then delete it and create a new one. After deleting the affected discovery, close Configuration Manager, restart Enterprise Reporter service, then open Configuration Manager.
