Hi,
I’ve been having issues with ag-grid, specifically on Streamlit Community Cloud platform deployment, too.
My issue is reported here:
https://discuss.streamlit.io/t/streamlit-aggrid-crashing-my-streamlit-application/30470/13?u=bkandel
And I have contacted support@streamlit.io without response yet.
I realized after multiple tests that the issue happens for users of the app, but not for me as a developer (meaning that if I authenticate with Github on Streamlit Cloud and run the app I have no problem, but if I run it as a user without Github authentication I do get the problem).
Like you, I am stuck with this problem and considering avoiding ag-grid component, which would make me very sad for the lost functionality!
