可能未处理的承诺拒绝id：0：TypeError：无法读取react-native-track-player中未定义的属性“标题”

如何解决可能未处理的承诺拒绝id：0：TypeError：无法读取react-native-track-player中未定义的属性“标题”

我创建了流派，每个流派都有一系列歌曲。我也有每个流派歌曲数组的 Player.js，但收到警告和 TypeError 消息：[Sun Apr 04 2021 05:49:58.513] WARN可能未处理的承诺拒绝（ID：0）： 类型错误：无法读取未定义的属性“标题” 类型错误：无法读取未定义的属性“标题”

当我尝试更改曲目时，我也收到此错误： [Sun Apr 04 2021 05:49:58.676] LOG track id -1 index 3 [Sun Apr 04 2021 05:49:58.690] 警告可能未处理的承诺拒绝（ID：1）： 类型错误：无法读取 null 的属性“scrollToOffset” 类型错误：无法读取 null 的属性“scrollToOffset”

我如何播放每种类型的歌曲。我需要这方面的帮助，两天前我一直在尝试解决这个问题。 下面是 hipHopPlayerScreen.js：

  View,SafeAreaView,Text,Image,FlatList,Dimensions,Animated,StyleSheet,TouchableOpacity,} from 'react-native';

const {width,height} = Dimensions.get('window');

export default function HipHopPlayerScreen() {

  const navigation = useNavigation();

  const slider = useRef(null);

  const index = useRef(0);

  const [hipHopsongIndex,setHipHopSongIndex] = useState(0);
  

  const isItFromUser = useRef(true);

  const position = useRef(Animated.divide(scrollX,width)).current;
  const playbackState = usePlaybackState();

  useEffect(() => {
    scrollX.addListener(({value}) => {
      const val = Math.round(value / width);

      setHipHopSongIndex(val);
    });

    TrackPlayer.setupPlayer().then(async () => {
      console.log('Player ready');
   
      await TrackPlayer.reset();
      await TrackPlayer.add(hiphopsongs);
      TrackPlayer.play();

      TrackPlayer.addEventListener(Event.PlaybackTrackChanged,async (e) => {
        console.log('song ended',e);

        const trackId = (await TrackPlayer.getCurrentTrack()) - 1;

        console.log('track id',trackId,'index',index.current);

        if (trackId !== index.current) {

    return () => {
