NetworkReader:ReadByte out of range:NetBuf sz:0 pos:0

I am using UNET (latest version), and Unity 2021.1, and I am getting this issue intermittently.

I know UNET is deprecated, and I have plans to port away from it, but I would like to know if thre is a solution to this issue, since it will take some time to port from UNET.

I can solve this issue with a combination of:
Removing and reinstalling HLAPI (Client and server) and
Rebuilding the Library.

I am also noticing odd issues with some messages, such as this one:

Code (CSharp):

1. public class testmessage : MessageBase
2. {
3.     public string testvariable;
4.     public string testdata;
5. }

It's pretty simple, but starting in 2021.1, I have noticed that sometimes the message variables seem to be blank, and I need to change the function, and rebuild the script, then it works for a while again.

I'm guessing these issues are just due to UNET slowly becoming obsolete, but is there anything I can do to patch it together for a while before I port?

 

uNet is outdated and forgotten that even the developers forgot to remove it...

Removing it is one thing, but they didn't announce an official replacement yet, so some of us are a little stuck!

 

The official replacement for UNet will be MLAPI. Right now MLAPI is still an experimental package but it will replace UNet in the future.

If you are looking for a networking library which is very similar to UNet but potentially more stable I can recommend to check out Mirror.

 

Mirror is exactly what I am looking at, it seems the upgrade path will be cleaner (For my setup at least) and easier than MLAPI.

Thanks.
