Resolved Why Netcode for GameObjects 1.5.1 doesn't target 2022.3

I tried to upgrade the Unity version from 2021.3 to 2022.3 after Netcode 1.5.1 upgrade but I got this error:

Code (CSharp):

1. Unity.Netcode.Editor.CodeGen.NetworkBehaviourILPP: (0,0): error  - System.NullReferenceException: Object reference not set to an instance of an object.|   at Unity.Netcode.Editor.CodeGen.NetworkBehaviourILPP.GenerateVariableInitialization(TypeDefinition type)|   at Unity.Netcode.Editor.CodeGen.NetworkBehaviourILPP.ProcessNetworkBehaviour(TypeDefinition typeDefinition, String[] assemblyDefines)|   at Unity.Netcode.Editor.CodeGen.NetworkBehaviourILPP.<>c__DisplayClass7_0.<Process>b__1(TypeDefinition b)|   at System.Collections.Generic.List`1.ForEach(Action`1 action)|   at Unity.Netcode.Editor.CodeGen.NetworkBehaviourILPP.Process(ICompiledAssembly compiledAssembly)   at Unity.Netcode.Editor.CodeGen.NetworkBehaviourILPP.GenerateVariableInitialization(TypeDefinition type)|   at Unity.Netcode.Editor.CodeGen.NetworkBehaviourILPP.ProcessNetworkBehaviour(TypeDefinition typeDefinition, String[] assemblyDefines)|   at Unity.Netcode.Editor.CodeGen.NetworkBehaviourILPP.<>c__DisplayClass7_0.<Process>b__1(TypeDefinition b)|   at System.Collections.Generic.List`1.ForEach(Action`1 action)|   at Unity.Netcode.Editor.CodeGen.NetworkBehaviourILPP.Process(ICompiledAssembly compiledAssembly)

Then I looked at requirements and saw this text.

Netcode for GameObjects targets the following Unity versions:
Unity 2020.3, 2021.1, 2021.2 and 2021.3

Is there any reason this?
Will 2022.3 version be target?
Or 2022.3 will just focus Netcode for Entities?

 

I don't think this error is related to the version.
Because I get this error 2021.3.26f1

upgraded to 2022.3 same error

 

I had same error in Unity 2021.3.14f1.
It seems that using generic type inheriting networkbehaviour make this error.
In my case, downgrading Netcode version to 1.3.1 solved this problem.

 

I had same error in Unity 2022.3.4f1. Downgraded Netcode version to 1.3.1. Works great now.

Yes that is works, but the idea of this thread is not find solution. It is about question and bug report.

 

I found the solution, if you gettin same error please visit github page.
