json schema of object inside array

I'm trying to write a json schema so I can use it to validate a response in Postman. I have the feeling I am almost there, but missing something obvious.

I've checked Q&A on stackoverflow, this page and everything else that came up on google when searching for json schema object inside array

I link 2 pieces of code:

1. Is my schema that needs a fix
2. Is te response I'm trying to validate with the schema.

Note: Postman does accept the schema, but when I intentionally make an error ("type": "number" when it is a string in the response) the test in Postman just passes as if everything is allright. I expect the test to fail.

Schema:

const resultaatSchema = {
"type": "object",
"properties": {
    "InputParameters": {"type": "object"},
    "Resultaat": {"type": "array",
    "items": {
        "Bedrijfsnaam": {"type": "number"},
        "Winkel": {"type": "string"},
        "Kvknummer": {"type": "string"},
        "Accountmanager": {"type": "object"},
        "Eigenaar": {"type": "object",
        "properties": {
            "Naam": {"type": "string"},
            "EmailAdres": {"type": "string"},
            "RegionaleUnive": {"type": "object",
            "properties": {
                "Naam": {"type": "string"},
                "Nummer": {"type": "number"}
                }
            }
           }
        }
      }
     }
    }

};
