[BUG] @plotly/dash-jupyterlab extension failed to build in JupyterLab running on a JupyterHub server

[tlvu]

Describe your context
Please provide us your environment, so we can easily reproduce the issue.

• replace the result of pip list | grep dash below

dash                         4.2.0
dash_leaflet                 1.0.15

Describe the bug

From https://dash.plotly.com/dash-in-jupyter:

"To use jupyterlab mode, you'll also need to build the @plotly/dash-jupyterlab extension. When you launch a new JupyterLab notebook after installing Dash, you'll be prompted to build @plotly/dash-jupyterlab."

If we do not need to use jupyterlab mode, is there a way to disable this annoying "please build" pop-up that appears everytime we logging into JupyterLab?

When logging into JupyterHub and starting a JupyterLab session, I see this pop-up:

After I clicked "Build", I get this:

So I tried a manually jupyter lab build and I get the following errors:

[LabBuildApp] JupyterLab 4.5.6

(...)

[LabBuildApp] Node v22.21.1

(...)

Expected behavior

The build pop-up works in the JupyterLab session or I can pre-build on the server with jupyter lab build.
