Discord RPC rapidjson/document.h Error

[Swagguss]

I've been getting errors with discord rpc, the error is this: C:\HaxeToolkit\haxe\lib\discord_rpc\git\lib\discord-rpc\src\serialization.h(13): fatal error C1083: Cannot open include file: 'rapidjson/document.h': No such file or directory

I have reinstalled discord rpc many times, with git, and without git, restarted my computer, updated haxe, and downgraded haxe, but i still get this error.
