Recursive external $ref gets resolved to itself when `bundle`

Code:

const parser = new JsonSchemaRefParser();
const spec = await parser.bundle(spec);

Output:

      "$ref": "#/components/schemas/Link/properties/schema/properties/not/definitions/linkDescription"

It most likely has something to do with the fact that the ref is recursive.

I’m not sure what you mean, I wasn’t offering options. The first code block was how I would expect it to be resolved, as you were expecting a “definitions” to be created for you by json-schema-ref-resolver and that’s not how it works.

The second code block was me asking if you could try something out to see if it also created unexpected behavior. I was not at this point suggesting you change everything at your company. 😃

Weird. Thanks for reporting it. Will investigate.
