"Property sourceFileMap is not allowed."

[dozingpip]

sourceFileMap attribute is not implemented for the godot-mono launch configuration type?

OS/device including version:

Windows 10

Issue description:

Basically, this is happening to me, but when I try the linked solution and add the sourceFileMap attribute to my godot-mono launch configuration it says "Property sourceFileMap is not allowed."
If I change the type to, for example, coreclr temporarily, it resolves that attribute fine (but obviously that wouldn't actually be able to launch my project correctly).
I need to use it because the PathMap setting doesn't work in VS Code otherwise. If I don't have sourceFileMap and I'm using PathMap, when I'm debugging in vs code and put a breakpoint anywhere, I get "Could not load source 'MapEditor.cs': No source available."

Are there any updates on this issue or some workarounds? I have the same issue but on Linux (ubuntu 22.04).
