It works as is. However, as soon as I switch to using 'adaptive' mutation, I get an error:
list indices must be integers or slices, not NoneType

My only modification to the example from the documentation page linked above:
versions: Python 3.11.4, PyGAD 3.1.0 on Linux x86_64.
pygad.gann module documentation includes an XOR Example.

Is enough to trigger the error. Same with:
I would appreciate seeing this bug fixed as I would like to use adaptive mutation.
Please let me know if more information is needed.
