richembed 字段可能不是空错误——我将如何解决这个问题？

Question

我在控制台上不断收到错误消息，提示 RichEmbed 字段可能不为空。当我为每个字段定义值时......这是代码：

if (cmd === `${prefix}suggest`) {
  // USAGE:
  // /suggest this is the suggestion

  const suggestion = args.join(' ').slice(22);

  const suggestEmbed = new Discord.RichEmbed()
      .setDescription('~~-------~~**__NEW SUGGESTION!__**~~-------~~')
      .setColor('#ff0000')
      .addField('Suggestion By', `${message.author} (${message.author.id})`)
      .addField('Channel', message.channel)
      .addField('Time', message.createdAt)
      .addField('Suggestion', suggestion)
      .setTimestamp()
      .setFooter('Use /invite to invite me to your server!');

  const suggestchannel = message.guild.channels.find(`name`, 'suggestions');
  if (!suggestchannel) return message.channel.send("Couldn't find suggestions channel. Please **create one for this command to work!**");


  message.delete().catch(O_o => {});
  suggestchannel.send({ embed: suggestEmbed });
}

这是错误：

(node:616) UnhandledPromiseRejectionWarning: RangeError: RichEmbed field values may not be empty.
    at RichEmbed.addField

我将不胜感激！提前谢谢！

Answer 1

首先，确保提供了args[1]。然后，假设args中的第一个字符串是命令，将suggestion的声明改为...

const suggestion = args.slice(1).join(' ');

编辑：还将建议字段的行更改为...

.addField('Suggestion', suggestion.length <= 1024 ? suggestion : suggestion.slice(0, 1020) + '...')

这将防止任何错误导致 suggestion 对于嵌入字段而言过长。

Answer 2

您不能在 RichEmbed 中添加整个对象作为值。您正在尝试输入 channel Object 作为 RichEmbed 值，这是不允许的。

我想你想将channel.name 添加到这个 RichEmbed 字段中。我更改了代码，所以它显示了频道的名称。

这是更正后的代码：

if (cmd === `${prefix}suggest`) {
    // USAGE:
    // /suggest this is the suggestion

    const suggestion = args.join(' ').slice(22);

    const suggestEmbed = new Discord.RichEmbed()
        .setDescription('~~-------~~**__NEW SUGGESTION!__**~~-------~~')
        .setColor('#ff0000')
        .addField('Suggestion By', `${message.author} (${message.author.id})`)
        .addField('Channel', message.channel.name)
        .addField('Time', message.createdAt)
        .addField('Suggestion', suggestion)
        .setTimestamp()
        .setFooter('Use /invite to invite me to your server!');

    const suggestchannel = message.guild.channels.find(`name`, 'suggestions');
    if (!suggestchannel) return message.channel.send("Couldn't find suggestions channel. Please **create one for this command to work!**");


    message.delete().catch(O_o => {});
    suggestchannel.send({ embed: suggestEmbed });
  }
