AWS-API gateway -- jsonschema child object should validate when parent object exists - aws-api-gateway

Question

I need to create Jsonschema for the following JSON input. Here properties under Vehicle like( Manufacturer, Model, etc) should be required only when Vehicle object exists.
{
"Manufacturer": "",
"Characteristics": {
"Starts": "new",
"vehicle": {
"Manufacturer": "hello",
"Model": "hh",
"Opening": "",
"Quantity": "",
"Principle": "",
"Type": ""
}
}
}
I tried the following JsonSchema but this works when Vehicle object is not there but if we rename Vehicle to some other ex: Vehicle1 it doesn't give an error. Please guide me on how to fix this.
{
"$schema": "http://json-schema.org/draft-07/schema",
"type": "object",
"properties": {
"Manufacturer": {
"type": [
"string",
"null"
]
},
"Characteristics": {
"type": "object",
"properties": {
"Starts": {
"type": [
"string",
"null"
]
},
"Vehicle": {
"$ref": "#/definitions/Vehicle"
}
},
"required": [
"Starts", "Vehcle"
]
}
},
"required": [
"Manufacturer"
],
"definitions": {
"Vehicle": {
"type": "object",
"properties": {
"Manufacturer": {
"type": [
"string",
"null"
]
},
"Model": {
"type": [
"string",
"null"
]
},
"Opening": {
"type": [
"string",
"null"
]
},
"PanelQuantity": {
"type": [
"string",
"null"
]
},
"Principle": {
"type": [
"string",
"null"
]
},
"Type": {
"type": [
"string",
"null"
]
}
},
"required": ["Manufacturer", "Model", "Opening", "Quantity", "Principle", "Type"]
}
}
}
Thanks,

Sounds like you want to add "additionalProperties": false -- which will generate an error if any other properties are present that aren't defined under properties.
