Validation in a custom definition property is not throwing any error

[franckweb]

I'm trying to validate employee id to be an integer but the following does not throw any errors.

Data:

{
	"id": 824,
	"employee": {
		"id": "text"
	}
}

Schema:

{
	"type": "object",
	"properties": {
		"id": {
			"type": "integer",
			"minimum": 1
		},
		"employee": {
			"$ref": "#/$defs/employee"
		}
	},
	"$defs": {
		"employee": {
			"type": "object",
			"title": "Employee",
			"·properties": {
				"id": {
					"type": "integer"
				}
			},
		}
	}
}

And when I add "required": ["id", "name"] inside "employee" definition I do get following error as expected since "name" property is not present:

array(1) {
  ["/employee"]=>
  array(1) {
    [0]=>
    string(42) "The required properties (name) are missing"
  }
}

Note: The "id" of the first object does validate integer vs string type.

Any idea why this is happening? I'm trying to do a clean POC for Opis Json Schema.
Any help appreciated.

Fixed!
"properties" key inside "employee" had an extra space. Looks like Prettier did not format it correctly!
