Description
It would be nice to have support for the discriminator object so that anyOf or oneOf schemas can return good validation errors.
Exemple schema:
{
"$ref": "#/$defs/Route",
"$defs": {
"MountainHiking": {
"type": "object",
"properties": {
"discipline": {
"type": "string",
"enum": ["mountain_hiking"]
},
"length": {
"type": "integer",
}
},
"required": ["discipline", "length"]
},
"AlpineClimbing": {
"type": "object",
"properties": {
"discipline": {
"type": "string",
"enum": ["alpine_climbing"]
},
"height": {
"type": "integer",
},
},
"required": ["discipline", "height"]
},
"Route": {
"discriminator": {
"propertyName": "discipline",
"mapping": {
"mountain_hiking": {"$ref": "#/$defs/MountainHiking"},
"alpine_climbing": {"$ref": "#/$defs/AlpineClimbing"},
}
},
"oneOf": [
{"$ref": "#/$defs/MountainHiking"},
{"$ref": "#/$defs/AlpineClimbing"},
]
}
}
}Example instance:
{
"discipline": "mountain_hiking",
"length": "bad_string"
}Current error:
....is not valid under any of the given schemas...
Expected error:
...'bad_string' is not of type integer...
