As one of the first bigger js/node projects I decided to make a discord bot using discord.js. Every user is able to add new messages to the repl.it (the website I host the bot on) database and read random ones. The bot is working fine so I wanted to make it reply with embeds because it looks better and that is where the problem is.

I don't get any errors when making the embed but when I try to send it to the chat it says that it can't send an empty message at the RequestHandler.execute. Here is the full error message:

/home/runner/anonymous-message/node_modules/discord.js/src/rest/RequestHandler.js:350
      throw new DiscordAPIError(data, res.status, request);
            ^

    at async RequestHandler.push (/home/runner/anonymous-message/node_modules/discord.js/src/rest/RequestHandler.js:51:14) {

    json: {
      content: undefined,

      embeds: undefined,

      attachments: undefined,
      sticker_ids: undefined
    },
    files: []
  }
}

And here is the full code:

const Discord = require("discord.js")
const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES"] })
const keepAlive = require("./server.js") //just a webserver that I combine with uptimerobot.com so the bot doesn't go offline

const Database = require("@replit/database")
const db = new Database()
client.login(process.env.TOKEN) //since all replits are public (unless you buy the premium) you can use the environment variables to keep somestuff private

let prefix = "msg "
let channel

let starterMessages = ["a random test message!", "Hello World!", "why is this not working"]

db.get("msgs", messages => {
  if (!messages || messages.length < 1) {
    db.set("msgs", starterMessages)
  }
})

client.on("ready", () => {
  console.log("bot is working")
})

client.on("messageCreate", (msg) => {
  channel = msg.channel.guild.channels.cache.get(msg.channel.id)

  switch (true) {
    case msg.content.toLowerCase().startsWith(prefix   "ping"):
      channel.send("the bot is working")
      break

    case msg.content.toLowerCase().startsWith(prefix   "send"):
      let exists = false
      let tempMsg = msg.content.slice(prefix.length   5, msg.length)
      if (tempMsg.length > 0) {
        db.get("msgs").then(messages => {
          for (i = 0; i < messages.length; i  ) {
            if (tempMsg.toLowerCase() === messages[i].toLowerCase()) { exists = true }
          }
          if (exists === false) {
            console.log(tempMsg)
            messages.push(tempMsg)
            db.set("msgs", messages)
            msg.delete() //deletes the message so no one knows who added it
          } else {
            console.log("message already exists") //all console logs are for debugging purposes
          }
        });
      }
      break

    case msg.content.toLowerCase().startsWith(prefix   "read"):
      db.get("msgs").then(messages => {
        let rndMsg = messages[Math.floor(Math.random() * messages.length)] //gets the random message from the database

        //Here I make the embed, it doesn't give any errors
        let newEmbed = new Discord.MessageEmbed()
          .setColor("#"   Math.floor(Math.random() * 16777215).toString(16))
          .setTitle("a message from a random stranger:")
          .setURL("https://www.youtube.com/watch?v=dQw4w9WgXcQ&ab_channel=RickAstley")
          .addFields({ name: rndMsg, value: `if you want to send one of these for other people to read? Type "${prefix}send [MESSAGE]"` })
          .setFooter({ text: `type "${prefix}help" in the chat for more info!` })

        msg.channel.send(newEmbed) //and here is the problem. Without this line it runs with no errors
      });                          
      break
  }

})

keepAlive() //function from the webserver

I couldn't find any answers to this problem on the internet so I'm hoping you can answer it. Thanks in advance!

CodePudding user response：

Since you're using (I assume) discord.js v13, the way to send embeds is this:

msg.channel.send({embeds: [newEmbed]});

That should solve your problem.
