类型错误：无法使用劈开命令读取NULL的属性(正在读取状态 [英] TypeError: Cannot read properties of null (reading 'status') using slash commands

问题描述

我使用的是discord.js V13，尝试使用成员在线状态检查其状态时收到以下错误：

错误：

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

    at WebSocketShard.onMessage (/home/runner/DinBot-Slash-CMDS/node_modules/discord.js/src/client/websocket/WebSocketShard.js:300:10)*

编码：

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

推荐答案

首先，确保启用了GUILD_PRESENCES意图：https://stackoverflow.com/a/68528046/6126373

在V13中，presence属性can now be null，因此请确保还使用optional chaining operator或通过检查member.presence是否为真来进行检查：

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

// OR

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