Virtuoso Sesame HTTP Repository Configuration, Exception

Question

I got a problem while configuring the Virtuoso Sesame HTTP Repository following the "Setup RDF4J or Sesame HTTP Repository" part of this web page, Virtuoso Sesame HTTP Repository Configuration and Usage

It threw the following Exception after I clicked the "create" button, I did not find the solution.

The full stack trace in the logs are:

And I tried "Setup RDF4J or Sesame Console Repository" part to create a virtuoso rdf store, still got an error:

What's wrong with my operations and what should I do?
BTW, my sesame was normal, and creating a store of another RDF type is successful except virtuoso. I have installed virtuoso through brew, and it works properly.

Appreciate that.

What is the version of Virtuoso being used?

Note that you need to be using the latest 7.2 release of either Commercial or Open Source, with the latest Providers for RDF4J.

Also, ensure these Providers are in the correct location, as the error being reported setting up the Console Repo indicates that the VirtuosoRepository is an unsupported repository type.
