I am trying to validate my JSON Schema using tv4.
It is working and validation returns True.
But, in my case the the JSON collection "first, second, and third" will not be available all time.
How do I write the schema in this situation?
My JSON Data
{
"checked": "OK",
"result": {
"first": {
"label": "First Label",
"value": 1
},
"second": {
"label": "second Label",
"value": 34
},
"third": {
"label": "Third Label",
"value": 28
}
}
}
JSON Schema
{

"$id": "http://example.com/example.json",

In JSON Schema, all properties are optional by default. Your schema explicitly declares those properties as required. To make them optional, remove that keyword: "required": ["first", "second", "third"]
