'NotImplementedError' object is not iterable

[satadrudas]

I am trying to implement the examples for inverse design given in the lumerical website. I keep getting this error.
I am using Ubuntu 22.04
Lumerical v222

Animation is outdated, you need to rewrite the Filemoviewriter to a compatible one, by using matplotlib earlier versions, or skip the optimisation animation.
