Hi @Kyle_Marcroft

Your anonymized code includes the following statement

unified_callback = CustomJS(
        args=dict(filter=filter, p=p,
                  controls_choice_show_toggle=controls_choice_show_toggle
                  ), code=''' ''')

However, there is no quantity filter defined. Moreover, filter is a built-in function in Python 3, which is the source of the error you are seeing, I believe. See https://docs.python.org/3/library/functions.html

I hope this helps.
