TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

I got this error after resetting my pc to reconnect to the testnet. Below is the full error note I got from the console. Although there is no change in the parameters i have been using before now, still same they are: Token, Address and the Header.

Traceback (most recent call last):

Can you update the SD?

pip3 install --upgrade py-algorand-sdk

Can you print the algod address you’re using in the code. Most likely, it’s None instead of a string.

The Algod address is correct and I’ve updated the kit. It look so weird.

Can you post a minimal example which replicates the problem?

Thank you Fabrice. It worked now.
