TypeError：无法使用斜杠命令读取 null 的属性（读取“状态”）

Question

我正在使用 discord.js v13，并且在尝试使用成员状态检查其状态时收到以下错误：

错误：

TypeError: Cannot read properties of null (reading 'status')

代码：

const members = interaction.guild.members.cache;
  .addField('Presencia', 
      `**Conectado:** ${members.filter(member => member.presence.status === 'online').size}\n` + 
      `**Ausentes:** ${members.filter(member => member.presence.status === 'idle').size}\n` + 
      `**No Molestar:** ${members.filter(member => member.presence.status === 'dnd').size}\n` + 
      `**Desconectado:** ${members.filter(member => member.presence.status === 'offline').size}\n` + '\u200b'
   )

首先，确保GUILD_PRESENCES Intent 已启用：https://stackoverflow.com/a/68528046/6126373

在 v13 中，presence 属性 can now be null，因此请确保您还使用 optional chaining operator 或通过检查 member.presence 是否为真：

members.filter((member) => member.presence?.status === 'online').size;

// OR

members.filter((member) => member.presence && member.presence.status === 'online').size;
