I’m having trouble with my new module.

In my OnlineSubsystemUnincModule.cpp I have IMPLEMENT_MODULE(FOnlineSubsystemUnincModule, OnlineSubsystemUninc);

In my ProjectName.uproject I have

{
        "Name": "OnlineSubsystemUninc",
        "Type": "Runtime",
        "LoadingPhase": "Default"
},

In my primary module’s .Build.cs I have

        PublicDependencyModuleNames.AddRange(new string[]
        {
            // Other modules...
            "OnlineSubsystemUninc"
        });

in the Modules array.

As a test, I added a Print() method to my FOnlineSubsystemUninc class, but when I build I receive the following error

Severity    Code    Description Project File    Line    Suppression State   Details
Error   LNK2019 unresolved external symbol "public: void __cdecl FOnlineSubsystemUninc::Print(void)" (?Print@FOnlineSubsystemUninc@@QEAAXXZ) referenced in function "public: void __cdecl AShadowNetworkCharacter::OnSelectPressed(void)" (?OnSelectPressed@AShadowNetworkCharacter@@QEAAXXZ)   ShadowNetwork   D:unincsnet-clientShadowNetworkIntermediateProjectFilesShadowNetworkCharacter.cpp.obj 1       

Below is the actual code trying to call the Print method

FOnlineSubsystemUninc* OnlineSubsystemUninc = static_cast<FOnlineSubsystemUninc*>(OnlineSubsystem);
if (OnlineSubsystemUninc == nullptr)
{
    UE_LOG(LogCharacter, Warning, TEXT("FOnlineSubsystemUninc static_cast failed"));
    return;
}
OnlineSubsystemUninc->Print(); // ERROR: causes unresolved external symbol

I’ve double checked all of the naming. I’ve looked online for days, but come up empty. Any help would be greatly appreciated.
