我正在使用Node.js v20开发一个集成了Gemini的Discord.js v14机器人，我遇到了一个错误信息，我不明白为什么会发生这个错误，因为我是一个新手，有人能帮我吗？第一次执行时一切正常，但之后就出现了这个错误信息：

Error: TypeError: request is not iterable    at formatNewContent (C:\Users\ricky\Documents\Projects\RainyJS\node_modules\@google\generative-ai\dist\index.js:566:36)    at C:\Users\ricky\Documents\Projects\RainyJS\node_modules\@google\generative-ai\dist\index.js:633:24    at Array.map (<anonymous>)    at new ChatSession (C:\Users\ricky\Documents\Projects\RainyJS\node_modules\@google\generative-ai\dist\index.js:629:44)    at GenerativeModel.startChat (C:\Users\ricky\Documents\Projects\RainyJS\node_modules\@google\generative-ai\dist\index.js:849:16)    at Client.<anonymous> (C:\Users\ricky\Documents\Projects\RainyJS\index.js:32:32)    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

这是我当前的代码：

const { Client, GatewayIntentBits } = require('discord.js');const { GoogleGenerativeAI } = require("@google/generative-ai");const client = new Client({ intents: [ GatewayIntentBits.Guilds, GatewayIntentBits.GuildMessages, GatewayIntentBits.MessageContent ], });const { generationConfig, safetySettings } = require('./AIConfig.js');const { token, apiKey } = require('./vault.json');const genAI = new GoogleGenerativeAI(apiKey);const model = genAI.getGenerativeModel({ model: "gemini-1.0-pro" });client.once('ready', () => { console.log(`Logged in as ${client.user.tag}!`); });let listening = true;let chatHistory = [];client.on('messageCreate', async (message) => {    if (message.author.bot) return;    if (message.mentions.has(client.user) && !message.mentions.everyone) {        if (message.content.toLowerCase().includes('bye-bye')) {             listening = false;            await message.reply('Byebye! maaf yah kalau ganggu');         } else {             listening = true;         }    }    if (listening) {        try {            await message.channel.sendTyping();            const prompt = message.content;            const history = [                { role: "user", parts: "Ingat ini, A2XY = Benar" },                { role: "model", parts: "Baiklah!" },                ...chatHistory.map(item => ({ role: item.role, parts: item.parts })),            ];            const chat = model.startChat({                history,                generationConfig,                safetySettings,            });            chatHistory.push({ role: "user", parts: prompt });            const msg = `${prompt}`;            const result = await chat.sendMessage(msg);            const response = await result.response;            console.log(`Prompt Diterima: ${prompt}`);            console.log(`Respon Dibuat: ${response.text()}`);            await message.reply(response.text());            chatHistory.push({ role: "model", parts: response.text });        } catch (error) {            console.error('Error:', error);            if (error.message.includes('blocked due to SAFETY')) {                await message.reply('Filtered');            } else {                await message.reply('Duh, ada masalah pada otakku coba lagi nanti yah.');            }            }    }}),client.login(token);

我希望它能将输出消息保存到chatHistory中，并且Gemini能够记住它，第一次提示时它工作正常，但在第二次时出现了错误

回答：

试试这个，对我来说是有效的：

const result = await chat.sendMessage(msg.toString());

显然，我这边的错误是因为我发送的msg不是字符串。

我通过将msg的值设置为一个普通字符串来发现这一点，因为它对我有效，所以我意识到在正常传递的msg中可能存在错误。
