The fields in nodes depend on the value of entity. That is, if entity = "pd", then nodes has some fields, while entity = " top " - nodes has completely different fields, despite the fact that they are strictly required. For some reason, the JSON string is accepted by the valid schema, even if there are no fields defined in nodes as required. I already entire head broke, where can be mistake in the most scheme?

This JSON is valid:
{
"virtual": [
{
"type": "bus",
"path": "VUS1",
"entity": "pde",
"nodes": [
{
"id": "vrt_1",
"type": "string",
"address": 1,
"nozzles": [1, 2, 3]
},
{
"id": "vrt_2",
"type": "string",
"address": 2,
"nozzles": [1, 2, 3]
}
]
},
{
"type": "bus",
"path": "VUS2",
"entity": "topaz",
"nodes": [
{
"uid": 1,
"utype": "string",
"uaddress": "false",
"unozzles": false
},
{
"uid": "vrt_1",
"utype": "string",
"uaddress": "false",
"unozzles": false
}
]
}
]
}
And this JSON should not be applied, but is considered valid:
{
"virtual": [
{
"type": "bus",
"path": "VUS1",
"entity": "pde",
"nodes": [
{
"id_not_valid": "failure",
"type": 1,
"address": false,
"nozzles": [1, 2, 3]
},
{
"id": "vrt_2",
"type": "string",
"address": false,
"nozzles": [1, 2, 3]
}
]
},
{
"type": "bus",
"path": "VUS2",
"entity": "topaz",
"nodes": [
{
"uid_not_valid": "failure",
"utype": 1,
"uaddress": "false",
"unozzles": false
}
]
}
]
}
In theory, the second JSON should not be validated. For several reasons:
- For entity= "pd", the required fields are "id", "type"," address "and"nozzles". In the second line of JSON instead the field "id" is replaced by the field "id_not_valid" - > the obligatory field " id " is absent and validation has to end in failure. The same for entity="top" - "the uid" is replaced by "id_not_valid"
- For entity= "pd", the address field is of type token, in the second JSON line it is set to false, which corresponds to the type "boolean", but validation still takes place (the same if you assign an array or string value to address). For entity="top" type, the type is string, but the integer value 1 assigned to it is also assumed by the validator to be the correct string.
But the online validators on the links below say that everything is OK and both JSON conform to the scheme.
So I believe there is an error in the scheme.
The scheme itself was made by this example Example of JSON schema compilation
Any comments and tips on fixing JSON-schema, please
