Discord机器人报错：getTextInputValue读取未定义属性

我在使用Discord机器人的文本命令时遇到问题，以下是该命令的代码：

const { MessageEmbed, Client, ContextMenuInteraction,MessageActionRow,MessageButton,Formatters } = require("discord.js");
const client = global.client;
const craneSchema = require("../schemas/channelSchema");
const { 
    TextInputBuilder, 
    ActionRowBuilder,
    EmbedBuilder, 
    ButtonBuilder,
    UserSelectMenuBuilder,
    ModalBuilder,
    ButtonStyle,
    TextInputStyle,
    ChannelType,
    TextInputComponent
    } = require("discord.js");
const raones = require("../schemas/channelSchema");

module.exports = {
    name:"Yasakla",
    type: 2,

    /**
 * @param {Client} client
 * @param {ContextMenuInteraction} interaction
 */

    run: async (interaction) => {

        const bannedMemberIdInput = interaction.fields.getTextInputValue("BANNED_MEMBER_ID");
                if(!req.channelId) return interaction.reply({ content: `Bir oda oluşturmalısınız.`, ephemeral: true });

                interaction.guild.channels.cache.get(req.channelId).permissionOverwrites.edit(bannedMemberIdInput, {
                    ViewChannel: false,
                    Connect: false
                })
                await craneSchema.findOneAndUpdate({ guildId: interaction.guild.id, channelId: req.channelId }, 
                    {
                        $push: { channelBanned: { memberId: bannedMemberIdInput } }
                    })
                    interaction.reply({ content: `<@${bannedMemberIdInput}> başarıyla kanala banlı olarak eklendi!` })
      
}
};

我不知道问题出在哪里……

问题分析与修复方案 #

核心报错原因

Cannot read properties of undefined (reading 'getTextInputValue') 是因为你写的是右键菜单命令（type:2），这类命令默认不会关联模态框输入，直接调用interaction.fields.getTextInputValue会导致interaction.fields为undefined，自然无法读取输入值。

其他代码问题

• 未定义req变量，req.channelId会直接引发新的报错
• 重复引入同一个数据库schema（craneSchema和raones），属于冗余代码

修复后的完整代码

const { Client, ContextMenuInteraction, ModalBuilder, TextInputBuilder, ActionRowBuilder, TextInputStyle } = require("discord.js");
const client = global.client;
const craneSchema = require("../schemas/channelSchema");

module.exports = {
    name:"Yasakla",
    type: 2,

    /**
     * @param {Client} client
     * @param {ContextMenuInteraction} interaction
     */
    run: async (interaction) => {
        // 创建模态框，让用户输入成员ID和目标频道ID
        const modal = new ModalBuilder()
            .setCustomId('ban_member_modal')
            .setTitle('成员频道封禁');

        // 成员ID输入框
        const memberIdInput = new TextInputBuilder()
            .setCustomId('BANNED_MEMBER_ID')
            .setLabel('输入要封禁的成员ID')
            .setStyle(TextInputStyle.Short)
            .setRequired(true);

        // 频道ID输入框
        const channelIdInput = new TextInputBuilder()
            .setCustomId('TARGET_CHANNEL_ID')
            .setLabel('输入目标频道ID')
            .setStyle(TextInputStyle.Short)
            .setRequired(true);

        // 将输入框添加到模态框行
        const firstRow = new ActionRowBuilder().addComponents(memberIdInput);
        const secondRow = new ActionRowBuilder().addComponents(channelIdInput);

        modal.addComponents(firstRow, secondRow);

        // 弹出模态框给用户
        await interaction.showModal(modal);

        // 等待用户提交模态框，设置1分钟超时时间
        const submitted = await interaction.awaitModalSubmit({
            time: 60000,
            filter: i => i.user.id === interaction.user.id,
        }).catch(() => {
            interaction.reply({ content: '操作超时或已取消', ephemeral: true });
            return null;
        });

        if (!submitted) return;

        // 从提交的模态框中获取输入值
        const bannedMemberId = submitted.fields.getTextInputValue('BANNED_MEMBER_ID');
        const channelId = submitted.fields.getTextInputValue('TARGET_CHANNEL_ID');

        // 验证目标频道是否存在
        const targetChannel = interaction.guild.channels.cache.get(channelId);
        if (!targetChannel) {
            return submitted.reply({ content: '指定的频道不存在，请检查ID是否正确', ephemeral: true });
        }

        try {
            // 设置频道权限，封禁指定成员
            await targetChannel.permissionOverwrites.edit(bannedMemberId, {
                ViewChannel: false,
                Connect: false
            });

            // 更新数据库，若文档不存在则自动创建
            await craneSchema.findOneAndUpdate(
                { guildId: interaction.guild.id, channelId: channelId },
                { $push: { channelBanned: { memberId: bannedMemberId } } },
                { upsert: true }
            );

            submitted.reply({ content: `<@${bannedMemberId}> 已成功被封禁该频道！`, ephemeral: true });
        } catch (error) {
            console.error(error);
            submitted.reply({ content: '操作失败，请检查成员ID和频道ID是否合法', ephemeral: true });
        }
    }
};
