Fernando, thanks a lot. Your solutions and explanation give me a good starting point to make it up and running.

After replacing the typescript with the ts-patch and adding other changes you are listed, I faced another problem. It was impossible to use import and export declarations.

```auto
error TS6131: Cannot compile modules using option 'outFile' unless the '--module' flag is 'amd' or 'system'

```

To overcome it I was forced to make additional changes in the local.yml

1. Changing

```auto
js_entrypoint: "build/index.js"

```

with

```auto
path: "/nakama/data/modules/build"

```

1. Replacing `"outFile": "./build/index.js",` with `"outDir": "./build"` in tsconfig,json
2. Replacing

```auto
COPY --from=node-builder /backend/build/*.js /nakama/data/modules/build/

```

with

```auto
COPY --from=node-builder /backend/build/ /nakama/data/modules/build/

```

in the Dockerfile.

Thanks a lot for the help.
