Getting error when trying to enable Free Microsoft Store Addins

I am just trying to enable the grave addon for minecraft bedrock. I am getting this error in the log.

I have copied the world from my local windows machine to the server. I am unsure as to why this doesnt work as ive added the required folders to the MC docker volume.

Start with the logged “Network port occupied” error and the Docker volume and copied-world configuration described in the issue. Check how the container’s server port is allocated and how the world is mounted; done means identifying the conflicting or missing configuration and documenting a reproducible setup.
