V2019-09 $ref cannot be resolved in array 'additionalItems' #493
Description
Hi, I encounter a reference problem in array 'additionalItems'. Here is my schema:
{
"$schema": "https://json-schema.org/draft/2019-09/schema",
"type": "object",
"additionalProperties": false,
"properties": {
"parameters": {
"type": "array",
"uniqueItems": true,
"items": [
{
"type": "object",
"required": [
"name",
"value"
],
"properties": {
"name": {
"const": "param-required"
},
"value": {
"anyOf": [
{
"$ref": "#/$defs/test-ref1"
},
{
"$ref": "#/$defs/test-ref2"
}
]
}
}
}
],
"additionalItems": {
"oneOf": [
{
"type": "object",
"required": [
"name",
"value"
],
"properties": {
"name": {
"const": "param-optional"
},
"value": {
"anyOf": [
{
"$ref": "#/$defs/test-ref1"
},
{
"$ref": "#/$defs/test-ref2"
}
]
}
}
}
]
},
"minItems": 1,
"maxItems": 2
}
},
"$defs": {
"test-ref1": {
"type": "string",
"pattern": "^\\{\\{.+\\}\\}$"
},
"test-ref2": {
"type": "integer"
}
}
}
When I try to validate the following data:
{
"parameters": [
{
"name": "param-required",
"value": 123
},
{
"name": "param-optional",
"value": "{{test}}"
}
]
}
I got the exception:
com.networknt.schema.JsonSchemaException: anyOf/$ref: Reference #/$defs/test-ref1 cannot be resolved

Seems when looping to 'findAncestor' from "$ref": "#/$defs/test-ref1", the 'root' is 'additionalItems' but not the root of the whole document. All reference works fine in 'items' section, only fails at 'additionalItems'. May I know if it is a bug? Or I need to copy all the '$defs' into 'additionalItems'?
