为什么在我运行命令时终端返回“无法发送空消息”？

Question

我正在尝试执行口袋妖怪命令，但由于某种原因，它返回为.这是代码，我希望这个平台能帮助我解决我的问题。UnhandledPromiseRejectionWarning: DiscordAPIError: Cannot send an empty messageconst rand = Math.floor(Math.random() * 802);const poke = rand > 0 ? rand : Math.floor(Math.random() * 802);const pokem = pokemon[poke];const embed = new Discord.MessageEmbed()  .setTitle("🕰️ Time is ticking!

您正在使用 编辑消息。由于消息只有嵌入，这将删除嵌入，因此没有要编辑消息的内容。{embed: null}

如果我正确解释代码，您希望更新嵌入，因此请使用以下内容：

// Using let here so that embed can be reassigned later

let embed = new Discord.MessageEmbed()

     .setTitle("🕰️ Time is ticking! You have 15 seconds to answer | WHO'S THAT POKEMON?!")

     .setColor(colored[~~(Math.random() * colored.length)])

     .setAuthor(message.member.displayName, message.author.displayAvatarURL())

     .setImage(pokem.imageURL)

// rest of code...

if (answer === pokem.name.toLowerCase()) {

 let embed = new Discord.MessageEmbed()

    .setTitle("<a:done:707045670661652481> Correct")

    .setColor(colored[~~(Math.random() * colored.length)])

    .setDescription(`Yatta! Well done, \`${pokem.name}\` was correct.`);

  // {embed} is shorthand for {embed: embed}

  await msg.edit({embed});

  return message.channel.send(embed);

}

// Instead of reassigning to embed, you could also create a new variable

embed = new Discord.MessageEmbed()

    .setTitle("<a:error:707045703003668521> Incorrect")

    .setColor(colored[~~(Math.random() * colored.length)])

    .setDescription(`Ba-Baka! You answered incorrectly, It was \`${pokem.name}\`.**`);

await msg.edit({embed});
