Use of $id in $ref is not working

[sunilgunisetty]

I have the following schema in 2 different files.

// ProductDescription.json
{
    "$schema" : "http://json-schema.org/draft-07/schema",
    "$id": "https://some-host.com/ProductDescription.json",
    "type": "object",
    "properties": {.
                   "uuid": {
                       "description": "The internal UUID uniquely identifying this entity",
                       "allOf": [
                           { "$ref": "/Types.json#uuid" }
                        ]
                    },    
       }
}

and

//Types.json
{
    "$schema" : "http://json-schema.org/draft-07/schema",
    "$id": "https://some-host.com/types.json",
    "definitions": {
        "uuid": {
            "$id": "#uuid",
            "type": "string",
            "pattern": "^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$"
        }
    }
}

When I try to load ProductDescription.json I get exception with a message a JSON pointer should start with '/' or '#/' .

I am using static load method in SchemaLoader class to load the schema.

In my front end I use ajv with the same files and it works without any issue.

Am I missing something / am I using wrong methods. Any suggestions is highly appreciated.

Hello @sunilgunisetty , for now I suggest using the { "$ref": "/Types.json#/definitions/uuid" } syntax, ie. referring to the subschema via a json pointer instead of its id.

I re-read the current version of the spec and I think what you ask for should work (though previous json schema drafts explained it differently). But it isn't covered by the official test suite, so I'm not 100% sure. Let's keep this issue open as a feature request.

@erosb Thank you.

I think this says it should work? https://json-schema.org/latest/json-schema-core.html#rfc.section.8.2.4

This is now fixed and released in version 1.12.0.
