output below warning.

E   DeprecationWarning: jsonschema.RefResolver is deprecated as of v4.18.0, in favor of the https://github.com/python-jsonschema/referencing library, which provides more compliant referencing behavior as well as more flexible APIs for customization. A future release will remove RefResolver. Please file a feature request (on referencing) if you are missing an API for the kind of customization you need.

Thanks for the heads-up. Will likely have to fix jsonscheme==4.17.3 until I can investigate the changes required to move to the new package.

If no-one started working on this, I can start working on this. But I do not know how much time I can dedicate to this

@peter-doggart , could you please let us know if this issue will be addressed in any of the upcoming releases?

[peter-doggart]

Yes, it will be. I just haven't had an opportunity to dig into it yet. The primary issue is that flask-restx generates swagger 2.0 type docs that require JSON types compatible with JSON-Schema Draft 4, which is really, really old now.
