Demo app is broken

[natea]

When I click on the link (https://share.streamlit.io/ines/spacy-streamlit-demo/master/app.py) to view the running app, it gives the following error:

TypeError: This app has encountered an error. The original error message is redacted to prevent data leaks. Full error details have been recorded in the logs (if you're on Streamlit Cloud, click on 'Manage app' in the lower right of your app).
Traceback:
