It's ctypes, not cpptypes. ctypes doesn't understand C++ classes like std::string. c_char_p represents a char* in the Orb structure. Change std::string to an char[MAX_NAME_LEN] array and use type c_char * MAX_NAME_LEN in Python.

Add a size parameter with the planet.size value and use it in your component.

To answer my own question (for anybody strugling with the same problem):

Make sure you don't have scalajs-java-time (1.0.0) as a dependency in your classpath. It is a incomplete library and if it is picked before scala-java-time you will receive the error posted in the question.

The reason this error occurred, was, that at least on my system, the ordering of the classpath changed from sbt 1.2.8 to sbt 1.3.x, which resulted in the scalajs-java-time library being picked before scala-java-time which resulted in the

Looks like your Map function is not mapping the galaxy object.

You can try see if Galaxy object is being populate removing it from Ok function and given it to a variable, after that you must place a breakpoint and see if the object is null or not, example:

It looks like you're inside an async computation expression that returns Async. So you should replace ignore with return () (where () is the unit value) so that all branches return the same type:

I have no idea on earth (pun intended) what all of those classes share in common. But whatever those are, may they be physical attributes would belong in some shared interface. The purpose would be to have shared method(s) that could be invoked. Remember an interface cannot have fields only public methods, expecting an implementation. For sake of simplicity, here's get and set.

In solarSystem.put(heavenlyBody.getName(), heavenlyBody); key Mars is put into hash map with value heavenlyBody. So the value references the object related to Mars.

Classes allow you to structure your data in meaningfull way, improving extensibility, maintainability and making your code easier to understand. If your main problem is to access systems from a class, you could just pass it as parameter. In modern C++ you should use std::vector or std::array instead of C-style-arrays. For example:
