A corrupt RPC packet crashes the game on Macs, but not anywhere else

Help Networking
1

Hey guys. Users of my game on Macs have reported crashes when playing the online multiplayer mode. The game never crashes in singleplayer, though. Their error logs reported that the game encountered a corrupt RPC packet and shut down to avoid any danger, or something. However, this never occurs on Windows.
Here’s the full error logs.

error logs

I’m thinking this might be happening because I use a third-party relay service to pass on RPC details to peers without sharing IPs. Here’s that resource:
https://www.nodetunnel.io/

I apologize if this help request doesn’t offer enough details to solve the problem: I can try to share other things if needed.

It was processing an RPC, but the program is illegally accessing memory, on the node with the rpc function, or during the function call.

Not sure what you may be passing in RPCs but usually you are only passing variants of native types, which in this case have successfully been parsed from the packet before the function call.

I can only speculate that the node with the target rpc function may have been deleted before being called. Or the function handling the RPC call is doing something risky during the rpc function.

I suspect less that it is the fault of the tunnel service, as udp packets do have checks at lower network layers, and Godot does some validation on its end.

Cant really go any further without being able to reproduce the issue yourself.

That would make sense, that’s something that happens in the game. Thanks pennyloafers! I’ll have a careful look at where things get deleted.

That’s the odd bit; the bug only happens on Macs, and at variable times. Since the issue might only happen sometimes, that makes sense, but the OS is throwing me off in terms of the fix.

Could you elaborate perhaps?

All but in one RPC, where I pass a class that I defined of type PlayerAttributes.

Got it.

This is highly possible.
