AttributeError: st.session_state has no attribute "_components_callbacks"

Custom Components streamlit-webrtc

Hey everyone!
I’m using the webrtc_streamer function from streamlit_webrtc like this:

from streamlit_webrtc import (RTCConfiguration,
    WebRtcMode,
    webrtc_streamer,
)

RTC_CONFIGURATION = RTCConfiguration(
    {"iceServers": [{"urls": ["stun:stun.l.google.com:19302"]}]}
)

def callback(frame: av.VideoFrame) -> av.VideoFrame:
    annotated_image = ...
    return av.VideoFrame.from_ndarray(annotated_image, format="bgr24")

webrtc_streamer(
        key="object-detection",
        mode=WebRtcMode.SENDRECV,
        rtc_configuration=RTC_CONFIGURATION,
        video_frame_callback=callback,
        media_stream_constraints={"video": True, "audio": False},
        async_processing=True,
    )

But whenever webrtc_streamer is called, I get this error :

AttributeError: st.session_state has no attribute "_components_callbacks". Did you forget to initialize it? More info: https://docs.streamlit.io/library/advanced-features/session-state#initialization

However, st.session_state is supposed to be initialized in the function register_callback from streamlit_webrtc.components_callbacks like this:

def register_callback(element_key, callback, *callback_args, **callback_kwargs):
    # Initialize callbacks store.
    if "_components_callbacks" not in _state:
        _state._components_callbacks = {}
    ...

So I don’t understand where is the problem.
I am using streamlit==1.17.0 and streamlit-webrtc==0.44.2.

Thank you in advance for any help!
