this same command works fine on ethereum mainnet for example:

>>> uniswap = Contract.from_explorer('0x1f9840a85d5af5bf1d1762f925bdaddc4201f984')
Fetching source of 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984 from api.etherscan.io...
>>>

How can it be fixed?

most likely an issue with the json formatting response from bscscan

Fill this in if you know how the bug could be fixed.

This fixed the issue for me:

brownie networks modify binance explorer="https://api.bscscan.com/api"

previously I was using the wrong explorer address https://bscscan.com/

Looks like I’m still having the issue.
