Invalid environment error with conda environment

[tleyden]

Description

When trying to set a custom conda environment, I get this error:

Reproduce

1. Download install the OSX (mac silicon) version of jupyterlab-desktop
2. Create a conda env with conda create --name my-conda-env python=3.11
3. Open JupyterLab desktop and create a new session in a directory
4. In the top right conda env picker menu (screenshot below) choose that conda env by navigating to /opt/miniconda/envs/my-conda-env/bin and choosing python
5. It gives an error about the conda env not being valid, but no other reasons about why it wasn't valid

Expected behavior

It should be a valid conda environment, so I wouldn't expect an error.

Context

• Operating System and version: OSX Ventura
• JupyterLab-Desktop version: 4.05-1
• Installer: .dmg

@tleyden I edited your issue to remove some values from the logs, I hope this is ok. You may want to check if there is anything else that needs to be sanitised.

[tleyden]

Ok thank you. I went ahead and deleted the logs. Let me know if you can still look at the issue without them

Is jupyterlab package installed in your environment? my-conda-env or self-query-experiment? If so what version?

[tleyden]

No it's not in my base conda env or in self-query-experiment, do I need to add it to either/both?

[krassowski]

Yes, as per https://github.com/jupyterlab/jupyterlab-desktop/blob/master/troubleshoot.md#dealing-with-custom-environment-server-launch-errors. This really should be shown in the UI though, the current error is not useful at all - this looks like regression. Can you confirm that installing the package fixes it?

[tleyden]

Yes that fixed it. I did the following:

conda activate self-query-experiment
pip install jupyterlab 
pip install ipykernel
python -m ipykernel install --user --name=self-query-experiment

And now in the jupyterlab desktop UI I'm able to to switch to that conda env.
