Webapp goes blank if one tries to render a dataframe with pd.Timedelta entries

See original GitHub issue

Summary

When I try to display a dataframe that contains a pd.Timedelta value, this causes the entire app to go blank.

Steps to reproduce

This webapp results in a blank screen

import streamlit as st
import pandas as pd 

df = pd.DataFrame({'timedelta':[pd.Timedelta(0)]})
st.write(df)

Expected behavior:

I’d expect to see a dataframe or an error message.

Actual behavior:

The screen is completely white (no error message)

Is this a regression?

I don’t know.

Debug info

Streamlit version: 0.88
Python version: 3.9
OS version: macOS Mojave
Browser version: Chrome Version 93.0.4577.63 (Official Build) (x86_64)

FYI this hasn’t been fixed in 0.89.0 (but the using the legacy serialization works) Error: Unrecognized type: "Duration" (18) is raised in the web browser

Closing this to keep the conversation about the broken support for timedelta type in this issue: https://github.com/streamlit/streamlit/issues/4489 There are also two workarounds as described here: https://github.com/streamlit/streamlit/issues/4489#issuecomment-1152402862
