Javascript 为什么我不能将变量传递给另一个函数中的函数？JS-REACT-NATIVE

对于noob的问题，我很抱歉，但我真的不明白为什么我会出现这个错误，我正在构建一个音乐播放器，我在componentDidMount中运行的第一个函数是requestPermissions，下面是代码：

try {
                let tracks = [];
                let tracks_object = []; 
                tracks = await MusicFiles.getAll({
                    cover: true,
                });
                for (i = 0 ; i < tracks.results.length ; i++) {
                    tracks_object.push(new Tracks_info(tracks.results[i]));
                }
                this.setState({tracks: tracks_object}, () => this.init_player());
            }catch(error) {
                alert(error);
            }

 init_player = async () => {
    try {
        if (this.state.random) {
            let random_tracks = this.random_queue(this.state.tracks);
            console.log(random_tracks);
        }else {
            await TrackPlayer.setupPlayer();
            await TrackPlayer.add(tracks);
            TrackPlayer.play();
        }
    }catch(error) {
        alert(error);
    }
}

 random_queue = (tracks) => {
    let cambio = tracks.slice().sort(() => {return Math.random() - 0.5});
    return cambio;
}

在我运行播放器之前，我确保随机音乐是否被激活，如果是，我将曲目传递到函数random queue，创建一个随机列表并返回，代码如下：

try {
                let tracks = [];
                let tracks_object = []; 
                tracks = await MusicFiles.getAll({
                    cover: true,
                });
                for (i = 0 ; i < tracks.results.length ; i++) {
                    tracks_object.push(new Tracks_info(tracks.results[i]));
                }
                this.setState({tracks: tracks_object}, () => this.init_player());
            }catch(error) {
                alert(error);
            }

 init_player = async () => {
    try {
        if (this.state.random) {
            let random_tracks = this.random_queue(this.state.tracks);
            console.log(random_tracks);
        }else {
            await TrackPlayer.setupPlayer();
            await TrackPlayer.add(tracks);
            TrackPlayer.play();
        }
    }catch(error) {
        alert(error);
    }
}

 random_queue = (tracks) => {
    let cambio = tracks.slice().sort(() => {return Math.random() - 0.5});
    return cambio;
}

它“起作用”，因为即使抛出错误，它也会返回数组，但不知道原因，错误如下：
