问题描述
我有这段代码console.log(newVoiceState.channel)在client.on("voiceStateUpdate", async (oldVoiceState, newVoiceState) => {内部返回：

但是当我尝试newVoiceState.channel.parentId时，我收到以下错误：

}
几乎所有其他channel.x属性都是相同的。例如，channel.guildId虽然在另一个中看得很清楚，但突然之间就不存在了。
这是如何可能的，我如何修复它？
推荐答案
每当成员更改其语音状态时都会发出voiceStateUpdate。在某些情况下，例如，当有人离开语音频道时，newVoiceState.channel将为null，如果您尝试读取此属性，它将抛出TypeError。
您需要比较更新前后的voiceState，以找出是什么触发了voiceStateUpdate事件。我刚刚添加了下面的一些代码和几个示例。如果有人加入/离开/切换频道，或者如果有其他更改(如自身静音/取消静音)，开始共享其屏幕等，则以下代码会记录这些更改：
client.on('voiceStateUpdate', (oldState, newState) => {
if (newState.channel && !oldState.channel)
console.log(
`${newState.member.displayName} has joined the voice channel "${newState.channel.name}"`
);
if (!newState.channel && oldState.channel)
console.log(
`${oldState.member.displayName} has left the voice channel "${oldState.channel.name}"`
);
if (newState.channel && oldState.channel) {
if (newState.channel.id !== oldState.channel.id) {
console.log(
`${newState.member.displayName} has left the voice channel "${oldState.channel.name}" and joined "${newState.channel.name}"`
);
} else {
console.log(
`${newState.member.displayName} is still in the voice channel "${oldState.channel.name}" but there were some changes (e.g. muted/unmuted themselves, started sharing their screen, etc.)`
);
}
}
});
