Structure File (NBT) not found after running /structure save in container

[nikshepsvn]

Describe the problem

Hi all, I'm working on a project to evaluate LLM performance using Minecraft. While trying to export the saved structure, no matter how hard I try, I cannot seem to find the file within the docker container. I was wondering if someone here could help me out. Is this an issue with permissions or am I missing something else?

when trying to load the file, with filename, within the container itself using /structure load however, it seems to work

thank you!

You're mounting relative host directory called "data":

    volumes:
      - ./data:/data

It'll be in there.
