installed the extension and now launcher does not work

[nick-youngblut]

Context

I'm using the JupyterLab Desktop app, and connecting to a Jupyter server running on a Slurm cluster.

I installed the jupyterlab-launchpad extension, refreshed the app, and then I could not open a new launcher (shift + command + L).

If I disable the jupyterlab-launchpad extension, then I can open a new launcher.

Value and/or benefit

It appears that the launcher is not working properly, at least with the JupyterLab desktop app (Version 4.2.1-1).

My jupyter environment that is used for running the server:

Anything else?

No response

@nick-youngblut thanks for reporting! It seems that the screenshot did not upload properly. Can you open the Developer Tools (its in the hamburger menu in JupyterLab Desktop) and paste the console logs after loading the application with launcher installed?

[nick-youngblut]

I've re-uploaded the screenshot. It was just a screenshot of the extension.

hmmm... the jupyterlab-launchpad extension now seems to work. I didn't change anything besides restarting the Jupyter server. I guess that I actually had to restart the server in order to get the extension working.

[krassowski]

Right, this extension includes a server extension hence the server needs a restart after installation. I opened #67 to document this.
