Default arguments for a function for module B of type module A

[vishwa2710]

Hello all!
I have a set of C++ repositories that utilize pybind11 to create python bindings.
https://github.com/open-space-collective
Specifically classes from Core are used heavily in other repos.

Everything compiles and runs fine the way it is setup currently.
However, when I try and run stubgen from mypy for the astrodynamics repo I get the following error:
OpenSpaceToolkitAstrodynamicsPy: Failed to import, skipping with error: arg(): could not convert default argument 'name: ostk::core::types::String' in method '<class 'ostk.astrodynamics.dynamics.Thruster'>.init' into a Python object (type not registered yet?)

This stems from the file Thruster.cpp where I am using ostk::core::types::String for a default value for one of the fields.

This issue does not occur when importing the modules as we have the following init.py where we do

from ostk.physics import *

(Physics imports IO and Math, which in turn import Core).

Any ideas on how I can resolve this issue? I looked into https://pybind11.readthedocs.io/en/stable/advanced/misc.html#partitioning-code-over-multiple-extension-modules but I was unable to figure it out.
