Jupyter-Dash no longer working in Jupyterlab 3.1.1?

[cammclean182]

Are there issues with Jupyter-Dash in Jupyterlab 3.1.1?

I've just created a new venv and installed the latest jupyterlab, dash, Jupyter-dash libraries. I'm trying to run the code from the example notebook in the repo.

When i run the cell for JupyterDash.infer_jupyter_proxy_config() i get the error:

c:\jupyter\venv\lib\site-packages\jupyter_dash\comms.py:69: RuntimeWarning: coroutine 'Kernel.do_one_iteration' was never awaited
kernel.do_one_iteration()
RuntimeWarning: Enable tracemalloc to get the object allocation traceback

Then the notebook becomes unresponsive until i restart the kernel.

Package versions are:

The extension looks like it was installed correctly. I installed jupyter-dash and then did a lab rebuild.

I've tried running this on my pc as well as in a docker container on my NAS. Both get the same issues.
