Cannot set cookie shortly after creating CookieManager #9

Closed muskedunder closed 3 years ago

muskedunder commented 3 years ago

If I try to set a cookie using a newly created CookieManager, I get errors saying st.session.state.cookies is None. Minimal example:

import time
import extra_streamlit_components as stx

SLEEP_TIME = 1

cookie_manager = stx.CookieManager()
time.sleep(SLEEP_TIME)
cookie_manager.set('yummy_cookie', "nomnom")

If SLEEP_TIME is too low I get the error

Fixed on 0.1.46. You can get the new update through pip.
