Hello, 

Thanks to you @fdutton for the fix.
I encountered some strange behavior with it.
I have tested the minContains with a very simple schema, but the error is a "contains" error and not a "minContains" error.

This is the sample schema :

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "$id": "schemas/samples/sample.mincontains.schema.json",
  "properties": {
    "myArray": {
      "type": "array",
      "minContains": 2,
      "contains": {"properties": {"itemType": {"const": "type A"}}
      },
      "items": {"properties": {"itemType": {"type": "string"}}}
    }
  }
}

And this is the document to validate with this schema :

{
  "$schema": "schemas/samples/sample.mincontains.schema.json",
  "myArray": [{"itemType": "type A"}]
}

This is the com.networknt.schema.ValidationMessage I have as result:

The ValidationMessage should have "minContains" as type value
I have tested the "normal" behavior on https://www.jsonschemavalidator.net/s/4KTe05B9
