                So you could override this value to trick those tools into using
                the generated OpenAPI. Have in mind that this is a hack. But if you
                avoid using features added in OpenAPI 3.1.0, it might work for your
                use case.

                This is not passed as a parameter to the `FastAPI` class to avoid
                giving the false idea that FastAPI would generate a different OpenAPI

    Convert any object to something that can be encoded in JSON.

    This is used internally by FastAPI to make sure anything you return can be
    encoded as JSON before it is sent to the client.

    You can also use it yourself, for example to convert objects before saving them
    in a database that supports only JSON.
