React JS Error on Pycharm Jupyter Startup

Hi

I encounter the following error on startup sometimes. 

11:08 AM Jupyter Javascript: Error: Minified React error #200; visit https://reactjs.org/docs/error-decoder.html?invariant=200 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

What ends up happening is the cells do not appear on the right hand side of pycharm, and the code doesnt run properly. Sometimes the cells do appear but they do not update as the code is 'running'

Restarting PyCharm fixes it
