Resolved [NetCode] Generated NetCode Method is Inaccessible from NetCode

As soon as I'm using a SendRpcCommandRequestComponent, I get the following error:

Code (Text):

1. MethodAccessException: Method `Networking.Generated.BUDNetworkingRpcCommandsGoInGameRequestCommandSerializer+InvokeExecute_00000053$BurstDirectCall.Invoke(Unity.NetCode.RpcExecutor/Parameters&)' is inaccessible from method `Networking.Generated.BUDNetworkingRpcCommandsGoInGameRequestCommandSerializer.InvokeExecute(Unity.NetCode.RpcExecutor/Parameters&)'
2. Networking.Generated.BUDNetworkingRpcCommandsGoInGameRequestCommandSerializer.InvokeExecute (Unity.NetCode.RpcExecutor+Parameters& parameters) (at Assets/NetCodeGenerated/Networking.Generated/BUD.Networking.RpcCommands.GoInGameRequestCommandSerializer.cs:29)
3. Unity.NetCode.RpcSystem+RpcExecJob.Execute (Unity.Entities.ArchetypeChunk chunk, System.Int32 chunkIndex, System.Int32 firstEntityIndex) (at Library/PackageCache/com.unity.netcode@0.5.0-preview.5/Runtime/Rpc/RpcSystem.cs:301)

These are calls from within NetCode to NetCode generated code – using NetCode 0.5.0-preview.5. What could be the issue? (Unsure where to look)

I'm using the following IRpcCommand:

Spoiler: GoInGameRequestCommand.cs

Code (CSharp):

1. public struct GoInGameRequestCommand : IRpcCommand
2. {
3. }

with this

Spoiler: GoInGameClientSystem.cs

Code (CSharp):

1. [UpdateInGroup(typeof(ClientSimulationSystemGroup))]
2. public class GoInGameClientSystem : ComponentSystem
3. {
4.     protected override void OnCreate() { }
5.  
6.     protected override void OnUpdate()
7.     {
8.         Entities.WithNone<NetworkStreamInGame>().
9.                  ForEach(
10.                          (Entity ent, ref NetworkIdComponent id) =>
11.                          {
12.                              PostUpdateCommands.AddComponent<NetworkStreamInGame>(ent);
13.                              var req = PostUpdateCommands.CreateEntity();
14.                              PostUpdateCommands.AddComponent<GoInGameRequestCommand>(req);
15.                              PostUpdateCommands.AddComponent(
16.                                                              req,
17.                                                              new SendRpcCommandRequestComponent
18.                                                                  { TargetConnection = ent }
19.                                                             );
20.                          }
21.                         );
22.     }
23. }

(basically the Getting Started code)

 

The issue was that I was too far ahead with my Burst version: 1.5.0-pre.3. Going back to 1.4.3 helped.
