Get wrong user id from ctx

Runtime Framework
1

I used two Unreal clients, A and B, to connect to the Nakama server locally. When Player A used an RPC to create a match, the creator ID was found to be the ID of Player B, which was obtained through ctx.Value(runtime.RUNTIME_CTX_USER_ID).(string). Is this a bug in Nakama?"

Hi @hexun80149128

Can you please let me know which version of Nakama server you are running and what version of the Unreal Nakama SDK you are using?

If you could also share the code you’re using to both authenticate with Nakama and call the RPC from the client, as well as the server side code that is logging the creator ID.

That information should help us diagnose the issue.

Thanks. Please check that the values being passed into the AuthenticateCustom call for ID and Username are unique for each client.
