Most Python objects aren't serializable into JSON. Pydantic isn't special in this sense.
What can you do about this? -- Well, if this is a one-of situation, then, maybe just do it by hand? If this is a recurring problem: json.dumps() takes a cls argument that will be used to do the serialization. Extend json.JSONEncoder and implement the encode() method for the encoder class you are passing. I believe that the official docs have some information about this too.
