OutOfBoundsDatetime

Since a short time I have an error

"OutOfBoundsDatetime: cannot convert input 737819.0 with the unit 'D'"

Nothing has changed since long time. It works on my localhost. I rebooted the app, deleted it and re-installed it on share.streamlit.io

https://share.streamlit.io/rcsmit/covidcases/main/number_of_cases_interactive.py

It is in this piece of code. It has always worked!

output['date'] = pd.to_datetime(output['date'], unit='D', origin=pd.Timestamp('1970-01-01'))
