我的机器人有问题...我收到错误消息

即使字段值不为空...谁能帮助我？这是发生错误的代码的sn-p：

case 'help':
        let command = interaction.options.getString('cmd', false);
        if(command === null)
            try{
                let embed = new Discord.MessageEmbed()
                    .setTitle('Help')
                    .setColor('ORANGE')
                    .setFooter('Use /help cmd:<command> for more informations on that command!')
                    .addField({ name: 'kill', value: /*'Kills the bot. (Only available to bot-helper role)'*/'hi' }) //line 2081
                    .addField({ name: 'ping', value: 'Get the time delay between when you send the message and when the bot detects it.' })
                    .addField({ name: 'snek', value: 'snek.' })

【解决方案1】：

addField 方法需要 3 个参数

embed.addField(name: string,value: string,inline: boolean)

你可以把你的代码改成这样：

case 'help':
let command = interaction.options.getString('cmd', false);
if(command === null)
    try{
        let embed = new Discord.MessageEmbed()
            .setTitle('Help')
            .setColor('ORANGE')
            .setFooter('Use /help cmd:<command> for more informations on that command!')
            .addField('kill', /*'Kills the bot. (Only available to bot-helper role)'*/'hi')
            .addField('ping', 'Get the time delay between when you send the message and when the bot detects it.')
            .addField('snek', 'snek.')
            .addField('stalk', 'Get notified when the user whith the specified id logs in. Only works with this server\'s members.')
            .addField('oc get', 'Get infos about an oc. Needs to have fetched the oc to the database from the message beforehand. See /help cmd:ocmessage.')
            .addField('oc edit', 'Allows for the owner of the oc to edit in the database in case the data is wrong.')
            .addField('quote', 'Starts a quizz about a quote. Guess the character who said that quote!')
            .addField('fac, flip a coin', 'Flips a swiss coin. Warning: There is 1 in 100000000000000000 chance that the piece lands on its side. Be careful!')
            .addField('hybridgen', 'A hybrid generator for you!')
            .addField('oc message', 'Adds a message to the database')
            .addField('help','Shows this message!');
        interaction.reply({embeds: [embed]});
    } catch (e) {
        console.warn(e);
    }
}

谢谢！我以为我必须指定它，因为它基于 object() 类型...

【解决方案2】：

我假设您只需要删除每个.addField 中的name: 和value:，例如：.addField('snek', 'snek.')，但您会收到另一个错误，因为您尝试使用interaction.reply(embed) 发送嵌入，并且您必须使用interaction.reply({embeds: [embed]}) 才能使其工作
