QualifiedValueShape constraint doesn't work on SHACL Playground

[ashleysommer]

Error in browser console:

Cannot find validator for constraint component http://www.w3.org/ns/shacl#QualifiedMinCountConstraintComponent

SHACL turtle:

ex:shape-01
    a sh:NodeShape ;
    sh:message "Exactly one sm:SubmissionManifest instance must be present in the file." ;  
    sh:targetSubjectsOf rdf:type ;
    sh:qualifiedValueShape ex:shape-02 ;
    sh:qualifiedMinCount 1 ;
    sh:qualifiedMaxCount 1 ;
.
ex:shape-02
  a sh:NodeShape ;
  sh:class sm:SubmissionManifest ;
.

I suspect the problem is that, according to the spec:

Node shapes cannot have any value for sh:qualifiedValueShape

so, ex:shape-01 should not be a node shape but a property shape (in order to have sh:qualifiedValueShape).

This is confirmed if you validate your shapes according to shacl-shacl.

The error message is not very informative, but it likely happens because there is no implementation of the constraint component for node shapes
