Example in View Parameters notebook not updating

[jlstevens]

Using holoviews 1.10, I get the following traceback in the web console (View_Parameters.ipynb notebook) when trying to switch to Scatter in the last example:

VM337:45 Python callback returned following output:

Actually, none of the widgets update that example right now, even just changing frequency and amplitude doesn't work. Eg. changing frequency gives this traceback in the web console:
