How to fix "TypeError: PokemonType.damage_multiplier() missing 1 required keyword-only argument: 'type_chart'"

[turibito]

Tried to run rl with new gym wrapper code and it gives out the following error.
Can you please tell me how to fix "PokemonType.damage_multiplier()".

You have to pass it a type chart for it to work. This code will help you. Is this a bug in poke-env or is this your code?

from poke_env.data import GenData
type_chart = GenData(9).type_chart
move.type.damage_multiplier(*target_mon.types, type_chart=type_chart)
