I am not sure exactly what is happening, but I suspect that it is cause by the line 'st.session_state.update(st.session_state)'. If you are trying to update a session state in Streamlit, it is best to do it as such: st.session_state['key'] = 'new value'.

@mkhorasani
i get the same error when using the following

def clear_session():
    st.session_state['doctxt'] = ''
    st.session_state['DOCfiles'] =  []

raise

StreamlitAPIException(SESSION_STATE_WRITES_NOT_ALLOWED_ERROR_TEXT)
streamlit.errors.StreamlitAPIException:
Values for st.button, st.download_button, st.file_uploader, st.data_editor,
st.chat_input, and st.form cannot be set using st.session_state.

I'm new to streamlit, and I thought this would be an easy thing to do, as it is in most languages.
I just need to clear everything out after a user is done processing so they can start a new entry. Is there a way to call a function in streamlit to reset or clear all the streamlit controls?
