After running conda update --all, everything seems to be working fine except for JupyterLab. I’m encountering a 500 Internal Server Error when trying to use it.
I’ve also tried creating a new Docker image using Micromamba, but JupyterLab isn’t working there either. This time, I’m getting a 404 Not Found error.
Has anyone else faced the same issue, or could you provide suggestions on how to resolve it?
There could be a number of issues. Can you paste the full error traceback?
Hi @krassowski ,
When I Open jupyter-lab in cli it is opening with below error
[W 2024-05-13 09:52:35.052 ServerApp] jupyterlab-extension-name | error adding extension (enabled: True): The module ‘jupyterlab-extension-name’ could not be found (No module named ‘jupyterlab-extension-name’). Are you sure the extension is installed?
Traceback (most recent call last):

jupyter_server.extension.utils.ExtensionModuleNotFound: The module ‘jupyterlab-extension-name’ could not be found (No module named ‘jupyterlab-extension-name’). Are you sure the extension is installed?
But GUI it is not opening at all.
This is likely unrelated - it is just a warning. Can you paste the full log, ideally when run with --debug flag? Does it show a URL to open in the browser at the end?
