react native FaceBook SDK get token for IOS is returning wrong signature

I am using the latest Facebook SDK react-native-fbsdk-next, I managed to make it work for Android, but it is not working for IOS

            LoginManager.logInWithPermissions([
              'public_profile',
              'instagram_basic',
              'instagram_manage_insights',
              'pages_show_list',
              'ads_management',
              'business_management',
              'ads_read',
              'read_insights',
            ]).then(
              (result: any) => {
                if (result.isCancelled) {
                  console.log('Login cancelled');
                } else {
                  if (Platform.OS === 'ios') {
                    AuthenticationToken.getAuthenticationTokenIOS().then(
                      (data: any) => {
                        console.log(
                          'after get accress token ',
                          data?.authenticationToken.toString(),
                        );

                        console.log(
                          'Login success with permissions: ' +
                            result.grantedPermissions.toString(),
                        );
                        //data.accessToken.toString()
                        dispatch(fetchPages(data?.authenticationToken));
                      },
                    );
                  }

I am getting a token, but when ever I try to use it to fetch pages, I get wrong signature. Any suggestions what might be the error? what I'm doing wrong.

const manager = new GraphRequestManager();
    const igAccountFields =
      'instagram_business_account{id,name,username,profile_picture_url},id,username,name,tasks,category,access_token';
    const req = new GraphRequest(
      '/me/accounts',
      {
        httpMethod: 'GET',
        accessToken: accessToken,
        parameters: {
          fields: {
            string: igAccountFields,
          },
        },
      },
      _responseInfoCallback,
    );
    manager.addRequest(req);
    manager.start();```
