json schema definition using conditional statements - json

Question

Iam trying to define an optional condition using json schema conditional statement (Using draft 7)
I have a json response like this.
[{
"views": [{
"name": "RSO Roster",
"displayOrder": 5,
"groups": [{
"type": "scrollable",
"displayOrder": 1,
"auditType": "player-pregame_roster",
"tiles": [{
"context": "event",
"dataStamp": 1535184247,
"tile_type": "person"
}, {
"context": "event",
"errorCode": 2,
"errorText": "seloger",
"tile_type": "person"
}
]
}
]
},
{
"name": "Leaders",
"displayOrder": 1,
"groups": [{
"type": "static",
"displayOrder": 1,
"tiles": [{
"context": "event",
"dataStamp": 1535184247,
"eventId":123
"tile_type": "static"
}
]
}
]
}
]
}]
In this response if the tile object contains the key errorCode the required field must be errorText and errorCode keys.Like wise
if the tile object doessnot contains any "errorCode" or "errorText" key then the tile item contains the required field "dataStamp".
To validate the above condition i have defined a schema like below.But it is not working.Whats wrong with my schema .
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "array",
"items": {
"type": "object",
"properties": {
"views": {
"$id": "views",
"type": "array",
"items": {
"$id": "views/items",
"type": "object",
"properties": {
"groups": {
"$id": "views/groups",
"type": "array",
"items": {
"$id": "views/groups/items",
"type": "object",
"properties": {
"tiles": {
"$id": "views/groups/tiles",
"type": "array",
"items": {
"$id": "views/groups/tiles/items",
"type": "object",
"properties": {
"dataStamp": {
"$id": "views/groups/tiles/dataStamp",
"type": "integer"
},
"tile_type": {
"$id": "views/groups/tiles/tile_type",
"type": "string"
},
"errorCode": {
"type": "integer",
"enum": [
2, 10
]
},
"errorText": {
"type": "string",
"enum": [
"seloger", "france24"
]
}
},
"if": {
"properties": {
"tile_type": {
"enum": ["person"]
},
"errorCode": {
"enum": [2, 10]
}
},
"required": ["errorCode", "errorText"]
}
}
}
},
"required": [
"type",
"tiles"
]
}
}
},
"required": [
"groups"
]
}
}
},
"required": [
"views"
]
}
}

Answer 1

The if statement is missing required in properties:
"if": {
"properties": {
"tile_type": {
"enum": ["person"]
},
"errorCode": {
"enum": [2, 10]
},
"required": ["errorCode"]
}
},
If there is no required the value of property is validated only if the property is set. So original if schema would pass any object without tile_type and errorCode.
https://stackoverflow.com/a/51034071/329463 might give you some inspiration on building exclusive properties clusters.
EDIT: modified full schema
