jsonschema with custom property - jsonschema

Question

I want to define a JsonSchema with a customProperty in it, this property follows some rules, so in order to validate those, I need to define a JsonSchema that will validate it.
So far I've managed to describe it properly, but it only works for the first level of attributes, and I want it to be recursive...
From my comprehension it should work, I probably made a mistake I'm unable to see and at this point I don't know if it's a bug, impossible, or stupid...
I believe redefining every type should be a possibility , but obviously I'd rather not.
Here is an example of the Json I want to validate
{
"title": "TheObject",
"type": "object",
"properties": {
"aString": {
"type": "string",
"myCustomProperty": {}
},
"anObjet": {
"type": "object",
"myCustomProperty": {},
"properties": {
"anotherObject": {
"type": "object",
"myCustomProperty": {}, //if this line is removed it still validates which I don't want
"properties": {}
}
}
}
}
}
and here is the JsonSchema I've done so far:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"properties": {
"title": {"type": "string"},
"type": {"type": "string","enum": ["object"]},
"properties": {
"type": "object",
"patternProperties": {
".*": {
"$ref": "#/definitions/Field"
}
}
}
},
"definitions": {
"Field": {
"type": "object",
"properties": {
"type": {
"type": "string"
},
"myCustomProperty": {
"$ref": "#/definitions/myCustomProperty"
},
"patternProperties": {
"^(?!myCustomProperty).*": {
"$ref": "#/definitions/Field"
}
}
},
"required": [
"type",
"myCustomProperty"
]
},
"myCustomProperty": {
//Some rules
}
}
}

I found a solution, I wasn't far from what I wanted after all.
In my definition of "Field", I am describing an object that defines an object, and I was missing the "properties" field. In which I had to put my recursive reference.
The right jsonSchema is the following :
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"properties": {
"title": {
"type": "string"
},
"type": {
"type": "string",
"enum": [
"object"
]
},
"properties": {
"type": "object",
"patternProperties": {
".*": {
"$ref": "#/definitions/Field"
}
}
}
},
"definitions": {
"Field": {
"type": "object",
"properties": {
"type": {
"type": "string"
},
"myCustomProperty": {
"$ref": "#/definitions/myCustomProperty"
},
"properties": { <==================== here
"type": "object",
"patternProperties": {
".*": {
"$ref": "#/definitions/Field"
}
}
}
},
"required": [
"type",
"myCustomProperty"
]
},
"myCustomProperty": {/*rules*/}
}
}
So far it works as expected, but if someone has a more elegant suggestion please share!
