Correcting syntax error at logging.

This is the wrong way to fix this. Basically you are removing f-strings which are a Python 3.6 feature. pyproject.toml indicates that this project is to be used with Python 3.6+ so using f-strings should be fine. If you need to remove the f-strings you should ensure that the variables still appear in the log messages.

Which version of Python are you using?
