Because of missing imports and some undefined variables the latest code wouldn't compile.
I have fixed it.
The only thing I am not sure about is dispatchConfig: PropTypes.bool.isRequired
Not sure if it's truly bool or if this is valid, but it works finally again, but with proper log timezone!
There were some build issues, also eslint was preventing build because of too old react-scripts, that was in conflict with another requirement for more recent eslint, so I've updated react-scripts, so newer eslint isn't a problem anymore.
