Consistency check - null

Hi,

I am working off an AEM 6.0 SP2 instance.  I am attempting to run a consistency check with the root "/" and fix inconsistencies set to "true", and the response it displays immediately is (null).

I cannot find any errors in any logs or anything that indicates an issue.

Can someone please advise if my parameters are invalid, or if there is some fix to this issue?

Thanks!
