I’m using a C# SDK (called MyGeotab) within Godot for a research project that I’m part of. I’ve verified that the (essentially) identical code works in a non-Godot context, but I get a pretty odd error when I use it within Godot. I’ve tried to change my .csproj variables to ensure consistency, but nothing has fixed the issue or changed it at all. The exception in question happens and is caught when awaiting an asynchronous authentication call to the API,
System.TypeInitializationException: The type initializer for 'Geotab.Checkmate.Web.WebServerInvoker' threw an exception. ---> System.NotImplementedException: The method or operation is not implemented.

In short, what I believe is happening is that the dependency stack that Godot uses is providing some different HTTP request stuff and it’s screwing with this SDK’s algorithm. I can’t prove this with my rather light experience with both C# and this SDK, that’s why I’m here.
The code that I’m running that produces this error is as follows. There’s other stuff running but it should not be interfering with this node at all, although I may try it in a separate project to see if that changes anything. The code that I’m running has a username and password in it, so I’ve intentionally replaced that with ~'s.
The error is occurring on the bolded line, await data.api.AuthenticateAsync(); which is where the authentication call to the API is made.
