A try with also with a minimal code and dont show the table. I tried with this code:
import streamlit as st
import pandas as pd
from st_aggrid import AgGrid
st.title("Test AgGrid")
df = pd.DataFrame({
"A": [1, 2, 3],
"B": ["x", "y", "z"]
})
st.dataframe(df)
AgGrid(df, key="test_grid")
Data frame is showed but aggrid dont.

I am getting a similar error that happens when pandas 3.x is installed.
When i pass a python dict that includes
np.nanorpd.natypes (eg. {'Test': np.nan}) to any component_func i get this error on the frontend:SyntaxError: Unexpected token 'N', ..." {"Test": NaN}, "imp"... is not valid JSONWith pandas 2.x installed they're treated correctly, a valid JSON is generated and the component loads correctly, but with pandas 3.x the component isn't even called.
Using python 3.14.3, streamlit 1.56.0 and pandas 3.0.2
