It should let you preview your notebook as a Panel in JupyterLab:

Looks like the serverextension that is responsible for running the endpoint isn’t running on your end though :confused:

Could you paste the output of jupyter serverextension list?

I also have this problem:

Config option `kernel_spec_manager_class` not recognized by `ListServerExtensionsApp`.
config dir: C:\Users\shh\.jupyter
    dask_labextension enabled
    - Validating...
      dask_labextension 5.1.0 ok

Got it to work by running jupyter serverextension enable panel.io.jupyter_server_extension
