ValueError when exporting ngen.config LSTM and BMIPython json schemas's

[aaraney]

I receive the following exception when exporting either LSTM's or BMIPython's json schema. Likewise, this affect all classes that either inherit or compose these classes.

ValueError: Value not declarable with JSON Schema, field: name='python_type_PyObject' type=PyObject required=True

I verified this issue is coming from use of pydantic.PyObject as a type hint is the above models. Ive not looked into possible solutions for this, but im sure we can figure out a work around.

Reproduce

from ngen.config.realization import Realization

with open("Realization.schema.json", "w") as fp:
    fp.write(Realization.schema_json(indent=2))
