Problem with the tutorials on the official YouTube channel not working

Hi everyone! I have been having some issues with the project on the sample tutorial not working as intended. After several tries (tried both the typescript and GO samples, having similar errors in both), I’m faced with this error:

  1. Versions: Nakama 3.3.0, Windows, and Docker
  2. Server Framework Runtime language (If relevant) Go, TS/JS

Here is the docker file:

FROM heroiclabs/nakama-pluginbuilder:3.3.0 AS builder

ENV GO111MODULE on

ENV CGO_ENABLED 1

WORKDIR /backend

COPY go.mod .

COPY *.go .

COPY vendor/ vendor/

RUN go build --trimpath --mod=vendor --buildmode=plugin -o ./backend.so

FROM heroiclabs/nakama:3.3.0

COPY --from=builder ./backend/backend.so /nakama/data/modules

COPY local.yml /nakama/data

Anyone has faced this and solved it?

On the typescript project, I have a “InitModule not found” error. That I can append here as well if needed

Hi @DoenitZ, it looks like you’re using a version of the nakama-common package that is incompatible with Nakama 3.3.0. Please can you check your go.mod file and ensure you’re using nakama-common v1.14.0.

To ensure you’re using the correct version of nakama and nakama-common please check the release dates for both:
