Hello @kingsley, please have a look at our [dependency pinning guide](https://heroiclabs.com/docs/nakama/server-framework/go-runtime/go-dependencies/). ---

So the issue was causes by **Go Runtime Version Mismatch** > Ensure you compile your Go server runtime module with the same version of Go as the Nakama binary was compiled with. The Nakama binary I was using was compiled with Go version `1.20.6`, and I compiled my runtime module with Go version `1.20.8`. Just use the same Go version to build the plugin should resolve the issue.
