Getting error from 'iloss_simulate' function

[tong-zipmex]

I copy and run this code

import defi.defi_tools as dft
dft.value_f, iloss = dft.iloss_simulate('cake','bnb', value=1000, base_pct_chg=50, quote_pct_chg=-25)

TypeError: unsupported operand type(s) for /: 'NoneType' and 'int'

Last month it's worked. But now.

Any update Please help.

Thanks a lot.

The library is already updated, there was a change in the pancakeswap API that I already implemented

you must reinstall the defi package

pip uninstall defi
pip install defi

this should work
