How to send a resource to a server?

Hi!
I’m trying to send a resource from a client to a server through a RPC method on Godot 4.2.1.
Now, directly sending the resource doesn’t work, thanks to a bug that throws a “resource_name hides a global script class” error. In the GitHub issue someone mentioned that using inst_to_dict() before sending and dict_to_inst() after receiving might solve the problem, however, I get the following error on the server:
Invalid instance dictionary format (can't load script at @path)
I did made sure that the resource has the same path on both the client and the server.
Maybe I’m just misunderstanding dict_to_inst()? There’s also a note in the docs about the method not working with built-in scripts, but honestly, I didn’t quite understand what that means.
Also, yes, there is another proposed workaround in the GitHub issue, that (as far as I understood) saves the resource to the disk, gets the file as a PackedByteArray, sends that to the server, the server saves that as a file and then opens it as a resource. But, like, this can’t be the best way to do this!? I just want to send a resource that contains three variables over to the server, and for that the workaround is way to complicated.

How do you send it? I think the step should be:

  • client
    • var data = inst_to_dict(object)
    • rpc(data)
  • server
    • dict_to_inst(data)

Also, you can debug it by printing data on both client and server, see what’s the diffrence.

Thank you, I’m just an idiot.
After printing the dictionaries, turns out that on the client, a folder was called “ressource”, but on the server it was called “resource”. I hate myself.
