express-openapi-validator: Endless loop caused by json-schema-ref-parser

Hello!

For some strange reason I yet not know, the “bundle” method of the class “$RefParser” seems to cause an endless loop on line 16: https://github.com/cdimascio/express-openapi-validator/blob/b8e34304ab5c2821a51c986e43b4b6ae4db51d05/src/framework/json.ref.schema.ts#L16

As I am the first one with this issue, maybe it is caused by my setup.

Those are my dependencies:

{
    "@typegoose/typegoose": "^6.1.5",
    "cors": "^2.8.5",
    "express": "^4.17.1",
    "express-openapi-validator": "^2.17.2",
    "express-session": "^1.17.0",
    "mongoose": "^5.7.12",
    "openid-client": "^3.8.3",
    "react": "^16.11.0",
    "react-dom": "^16.11.0",
    "swagger-ui-express": "^4.1.2",
    "webpack-pwa-manifest": "^4.0.0",
    "workbox-webpack-plugin": "^3.6.3",
    "yamljs": "^0.3.0"
  }

I also tried using different OpenAPI specs (also the one in the tests directory of this repo), with the same result.

Maybe it’s a dependecy conflict somehow?
