Error trying to deserialize with bytes_to_var_with_objects

Issue description

I'm trying to turn an object into a PackedByteArray so I can send it across an RPC call. However, when I try to deserialize, it I get an error saying ParserError: Class "Foo" hides a global script class. This only happens if I include the line with bytes_to_var_with_objects in the script.

Steps to reproduce

Just run the following lines. This seems to be causing the error:

	var foo:Foo = Foo.new()
	foo.alpha = 6
	foo.beta = 5
	
	var bytes:PackedByteArray = var_to_bytes_with_objects(foo)
	var foo_clone:Foo = bytes_to_var_with_objects(bytes)

This is Foo:

extends Resource
class_name Foo

var alpha:int
var beta:float

Looks like the same issue as:

• Class "XXX" hides global script class on FileAccess.get_var() #68666

This is still an issue and can make some things more complex, especially networking, which uses bytes_to_var_with_objects in put_var if objects are allowed.

Here's a simple reproduction script if it helps:

class_name Foo
extends Node

func _ready() -> void:
	var dict = {object = self}
	
	var encoded = var_to_bytes_with_objects(dict)
	
	var object = bytes_to_var_with_objects(encoded)

Hoping this gets fixed soon. Will probably just use var_to_str and str_to_var on all objects.

no fix yet ? :(

Please try 4.3.dev6, this might have been fixed assuming it's the same as #68666

Wow, nice, finally can use this in rpc() functions.

Thanks, keep up the Lords work!!

• Duplicate of Class "XXX" hides global script class on FileAccess.get_var() #68666 (uses the same mechanism under the hood).
• Fixed by Core: Add typed array support for binary serialization #78219 and Core: Fix RefCounted handling in marshalls.cpp #90693 for future 4.3.

Thanks for reporting the bug nonetheless!
