Need example how to call an endpoint with an untyped JSON POST body

[jasonswearingen]

Hello, I am having a difficult time finding documentation on how to send an untyped json post body to a kiota generated client endpoint.

There are some question posts, but no definitive answer with a solution:

• Proper way to use UntypedNode #4909
  • no answer presented
• Turning a json string into an UntypedNode #6681
  • the self-answer does not work in current Kiota, it throws an InvalidOperationException dealing with the UntypedObject deserialization
• https://learn.microsoft.com/en-us/openapi/kiota/serialization?tabs=csharp#untyped-node
  • I have figured out the way to manually convert my json to the shape of UntypedNode, which works, but requires the developer to know the shape before hand, or write their own dynamic parser that will convert arbitrary json to UntypedNode.

This seems like a pretty common path, what is the simple solution I'm missing?

I'm prototyping in C#, but will use typescript too (I would expect solutions to be similar)
