javascript - richembed 字段可能不为空错误 -- 我该如何解决这个问题？

Question

我的控制台上不断出现错误，提示 RichEmbed 字段可能不为空。当我为每个字段定义了值时...以下是代码:

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

我希望得到一些帮助!预先感谢您!

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 的声明更改为...

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) + '...')

这将防止任何导致建议对于嵌入字段来说太长的错误。
