Hello, I'm trying to add a jupyterlab utility to my meltano project in docker. I'm following this guide: https://docs.meltano.com/tutorials/jupyter/ However when trying to reach the lab GUI after starting it i get a connection refused error when clicking the link provided by the logs to reach the GUI. Do you have any idea why?

Hey @jannis_voigt, that article was written before we added the

notebook

utility to Meltano Hub. If your goal is to run a notebook, try giving that a go: https://hub.meltano.com/utilities/notebook 😄

Does this also work for interactively developing a notebook with a GUI? If I understood it correctly it only runs complete notebooks in one run.

Yeah, its a notebook converter and runner designed to be compatible with

meltano run

.

So this means i cannot develope with a GUI?

I've never tried the tutorial you linked, so I can't answer that for sure. What are you trying to achieve by launching the GUI through Meltano?

The way my project works right now (using matatika as utility) I have to rebuild it every time i change the code in my notebook. I want to be able to develope in the containerized environment so I can be sure the notebooks are also working when the Docker project is ran on another machine.
