Discord.js v14报错：期望对象却收到字符串的问题求助

问题根源 #

1. 错误修改Guild实例内置属性：直接给interaction.guild.owner赋值会破坏Discord.js内部对象结构，且后续拼接字符串的方式不符合addFields的参数要求。
2. addFields调用格式错误：Discord.js v14中，EmbedBuilder.addFields()要求传入包含name和value的对象数组，而非直接传入拼接好的字符串，这是导致类型不匹配报错的核心原因。

修复代码 #

run: async (client, interaction, args) => {
    let msg = await interaction.reply(`Checking..`);
    let boosts = interaction.guild.premiumSubscriptionCount;
    const ar = "<a:yes:962966293764505620>";
    // 用独立变量存储所有者信息，不修改Guild内置属性
    const owner = await interaction.guild.fetchOwner().then(m => m.user).catch(() => "Unknown Owner");
    
    var boostlevel = "0";
    if (boosts >= 14) boostlevel = "3 / ∞";
    else if (boosts >= 7) boostlevel = "2";
    else if (boosts >= 2) boostlevel = "1";

    let maxbitrate = 96000;
    if (boosts >= 14) maxbitrate = 384000;
    else if (boosts >= 7) maxbitrate = 256000;
    else if (boosts >= 2) maxbitrate = 128000;

    const emb = new EmbedBuilder()
        .setColor("Aqua")
        .setTitle(`Server info of ${interaction.guild.name}`)
        .setImage(interaction.guild.bannerURL({ size: 4096 }))
        // 按要求传入字段对象数组，每个字段包含name和value
        .addFields(
            { name: `${ar} Server Owner`, value: owner === "Unknown Owner" ? owner : `<@${owner.id}>` },
            { name: `${ar} Boost Level`, value: boostlevel },
            { name: `${ar} Max Bitrate`, value: `${maxbitrate}bps` }
        )
        .setThumbnail(client.user.displayAvatarURL({ dynamic: true }))
        .setFooter({
            text: `Command Requested by: ${interaction.user.tag}`,
            iconURL: interaction.user.displayAvatarURL(),
        });

    setTimeout(() => {
        msg.edit({ content: ` `, embeds: [emb] });
    }, 500);
},
};

关键修改说明 #

• 移除interaction.guild.owner的赋值操作，改用owner变量存储获取到的用户对象或错误提示
• 调整boostlevel和maxbitrate的判断逻辑为else if，避免重复覆盖值
• addFields传入多个字段对象，每个对象明确包含name（字段标题）和value（字段内容）
• 处理fetchOwner失败的情况，返回友好提示
