How can I run the dash app successfully on JupyterHub?

Hello everyone.
I’m trying to use dash on jupyterhub, but the output is grayed out without any errors.How can I resolve it?

Environment information is below.

versions

jupyterhub = “==4.0.2”
jupyterlab = “==4.0.9”
dash = “==3.0.4”

extensions

~$ jupyter labextension list

JupyterLab v4.0.9
@jupyterhub/jupyter-server-proxy v4.4.0 enabled OK
@plotly/dash-jupyterlab v0.4.3 enabled OK

I ran the command, “jupyter lab build”.

I would be grateful if you could answer my question.

Usually when this happens, there are errors in the browser console. Looking at them can give you some leads. If not, please post both JupyterLab logs and browser console logs!

Thank you for your advice.

It worked fine if I paid attention to the following:

  • Set Up Proxy Path for JupyterHub
  • Run Dash in the Background

So, I’ll close this topic.
