Impossible to bundle JSON Schema draft-04 itself.

[robertmassaioli]

Here is my basic schema:

{
    "$schema": "http://json-schema.org/draft-07/schema#",
    "additionalProperties": false,
    "properties": {
        "schema": {
            "$ref": "http://json-schema.org/draft-04/schema",
            "title": "schema"
        },
        "tags": {
            "items": {
                "enum": [
                    "forge"
                ],
                "type": "string"
            },
            "title": "tags",
            "type": "array"
        },
    },
    "required": [
        "schema"
    ],
    "type": "object"
}

My code is:

const $RefParser = require('json-schema-ref-parser');

$RefParser.bundle("schema.json").then(schema => {
   console.log(JSON.stringify(schema, null, 2));
}).catch(e => {
   console.error(e);
});

As you can see in "$ref": "http://json-schema.org/draft-04/schema",, I want to bundle the draft-04 schema. Instead, my output is:

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "additionalProperties": false,
  "properties": {
    "schema": {
      "$ref": "#/properties/schema/properties/not",
      "title": "schema"
    },
    "tags": {
      "items": {
        "enum": [
          "forge"
        ],
        "type": "string"
      },
      "title": "tags",
      "type": "array"
    }
  },
  "required": [
    "schema"
  ],
  "type": "object"
}

That's not even a valid schema. This looks like a bug to me but I would be very interested in understanding what I have done wrong.

Can somebody please confirm if this is a bug? Cheers.

Oh, here is a complete bundle of a sample app. error-example.zip

Can you expand on why this needs to work? Not sure of the use case or what is happening, the issue is pretty sparse.

[robertmassaioli]

@philsturgeon If I want to have a JSON value, that contains a JSON Schema at v4, then I should be able to just reference the v4 schema as a validator. And then when I run the bundle tool here on it, it should make sure that it is bundled inline and that everything works as expected.

[robertmassaioli]

What do I need to provide such that the use case is easier to understand here? I'm confused that it's not clear that this is a bug and what the expected output would be.

[philsturgeon]

What tool are you passing this JSON value too that it needs the JSON Schema $schema definition bundled in? Why would a tool want or need that to be done?
