Fablib can not list resources via jupyterhub

Hi,

I am trying to list site resources using the following code snippet

try:
fablib.list_sites()
except Exception as e:
print(f”Exception: {e}”)

but it throws error : ” Exception: unconverted data remains: +0000 ”

detailed error is given below

To recreate on your end, I’m following the example notebook list_selected_resources.ipynb under jupyter-examples-rel1.6.1/fablib_api/sites_and_resources/

Note: I had previously been using jupyter notebook to list and create my own slices

Thanks,
Khawar
