TypeError: is_list_like() takes 1 positional argument but 2 were given

I never had this error until recently. When I do impact.run(), I see the following error:

`--------------------------------------------------------------------------- TypeError Traceback (most recent call last) in ----> 1 impact.run()

TypeError: is_list_like() takes 1 positional argument but 2 were given`

It looks to me like is_list_like in this instance does not need the second argument, namely "list". Not sure how that suddenly became a problem on my end however.
