okld / streamlit-elements-demo Goto Github PK

Hi, could you please provide me guidance how to overcome the following error:

File "/Users/UsrAlpha/opt/anaconda3/envs/elements/lib/python3.10/site-packages/streamlit/runtime/state/session_state.py", line 440, in getitem
raise KeyError(_missing_key_error_message(key))
KeyError: 'st.session_state has no key "streamlit_elements.core.callback.elements_callback_manager". Did you forget to initialize it? More info: https://docs.streamlit.io/library/advanced-features/session-state#initialization'
(tickets_copy) F3095:streamlit-elements-demo-main UsrAlpha$

this is when trying to replicate your work(https://github.com/okld/streamlit-elements-demo)...for any other simple attempt I tried (your example in the forum or another repositories), I got the same error...

after recreating several times my environments, my latest one has the following versions:

streamlit version : 1.12.2
streamlit_elements version : 0.1.0

thank you
