react native – Issue with joining Agora channel and logging in agora-rnuikit – JOIN_CHANNEL_ERR_USER_NOT_LOGGED_IN

I am using the Agora React Native UIKit (agora-rn-uikit) to integrate Agora’s video call functionality into my React Native application. However, I am encountering an issue where I am unable to join a channel after logging in. Specifically, when I attempt to join a channel, I receive the errors:

• ConnectionStateChanged CONNECTING LOGIN,
• login error Error: LOGIN_ERR_REJECTED,
• join RTM channel rmhpjfub,
• ConnectionStateChanged DISCONNECTED LOGIN_FAILURE,
• joinChannelError: Error: JOIN_CHANNEL_ERR_USER_NOT_LOGGED_IN,
• sendMessage Error: CHANNEL_MESSAGE_ERR_USER_NOT_LOGGED_IN,

Here is the code I’m using to log in and join the channel:

   const initializeSession = async () => {
     try {
       setLoading(true);
         const res = await fetchSession(session_id, token);
          if (res) {
             console.log('Session:', res?.info?.session?.channel);
             setConnectionData({
               appId: agoraAppId,
               channel: res?.info?.session?.channel,
               rtmUid: userId,
               username: user.user_type == 'doctor' ? 'Doctor' : 'Patient',
               rtmToken: null,
               rtcToken: null,
             });
           }
      } catch (error) {
           console.error('Error fetching session:', error);
         } finally {
           setLoading(false);
         }
       };

   initializeSession();
}, []);
