had your exact same error: the code inside update_data is actually correct.
What i did to fix the problem is: removed and reinstalled python3 on my ubuntu vm.
For example take a look here: https://askubuntu.com/questions/897628/how-to-restore-after-accidentally-apt-get-remove-python...just dont close the terminal while doing this (otherwise you need to install some temrinal emulator like xterm)
I also used venv to create an isolated env afterwards (could be a good thing to try it before refreshing python3 install)
