RangeError [EMBED_FIELD_VALUE]：MessageEmbed 字段值必须是非空字符串

Question

所以我目前正在尝试将我的 Discord 机器人从 V12 更新到 V13，我目前遇到了一个非常令人沮丧的问题。因此，基本上我正在创建一种事件命令，人们可以在其中做出反应以参加，每次有人对嵌入编辑本身和问题所在做出反应时。那么我是如何做到的 V12 是我通过更新值的函数编辑了消息。

message.edit({
    embeds: [
        await updateEmbed(
            embedPref,
            users[0],
            users[1],
            users[2],
            displayText[0],
            displayText[1],
            displayText[2],
            displayText[3]
        ),
    ],
});

由于错误的性质，我认为这不是问题的根源。这是Embeds更新的代码：

function updateEmbed(option, users1, users2, users3, ...displayText) {
const upatedDndEmbed = new Discord.MessageEmbed()
    .setTitle(`**D&D** at ${displayTime}`)
    .setThumbnail("https://i.imgur.com/u0aN19t.png")
    .setDescription(displayText[0])
    .setColor("DC143C")
    .addFields(
        { name: "\u200B", value: "\u200B" },
        { name: "Campaign:", value: `${displayText[1]}`, inline: true },
        { name: "DM:", value: `${displayText[2]}`, inline: true },
        { name: "Whereabout:", value: `${displayText[3]}`, inline: true },
        { name: "\u200B", value: "\u200B" },
        {
            name: `<:accepted:867150417271324672>Accepted (${users1.length}/${memberCount})`,
            value: users1.length !== 0 ? users1 : "-",
            inline: true,
        },
        {
            name: `<:unsure:867150452423131166>Unsure (${users2.length}/${memberCount})`,
            value: users2.length !== 0 ? users2 : "-",

        {

            value: users3.length !== 0 ? users3 : "-",
            inline: true,
        }
    )
    .setFooter(`This message was issued by ${msgSender}`)
    .setTimestamp(new Date());

console.log("I got here 2 ");

const upatedGameEventEmbed = new Discord.MessageEmbed()
    .setTitle(`**Game Event** at ${displayTime}`)

    .setFooter(`This message was issued by ${msgSender}`)
    .setTimestamp(new Date());

return option === 1 ? upatedDndEmbed : option === 2 ? upatedGameEventEmbed : upatedEventEmbed;

}

这段代码在 V12 中运行良好，但现在返回错误：

RangeError [EMBED_FIELD_VALUE]：MessageEmbed 字段值必须是 非空字符串。

编辑：所以我发现了问题，显然你不能将数组作为字段的值。这就解释了为什么这不起作用。

Answer 1

尝试替换您设置的值

users1.length !== 0 ? users1 : "-"

到

users1 || "-"

也许users1 是array，也许users1.length 正在返回你undefined 或null 而不是0，所以使用它自己看看，如果它仍然不起作用，之前创建嵌入使用

console.log([users1,users2,users3,displayText...])

确定这些变量到底是什么。

Answer 2

根据https://discordjs.guide/additional-info/changes-in-v13.html#strings 需要通过方法.toString() 或模板文字进行验证。我的代码没有。所以为了解决这个问题，我在所有用户数组之后添加了.join("\n")。这实质上是用换行符分割数组中的所有元素。固定代码：

    function updateEmbed(option, users1, users2, users3, ...displayText) {
        const users1Length = users1.length;
        const users2Length = users2.length;
        const users3Length = users3.length;

        const updatedDndEmbed = new Discord.MessageEmbed()
            .setTitle(`**D&D** at ${displayTime}`)
            .setThumbnail("https://i.imgur.com/u0aN19t.png")
            .setDescription(displayText[0])
            .setColor("DC143C")
            .addFields(
                { name: "\u200B", value: "\u200B" },
                { name: "Campaign:", value: `${displayText[1]}`, inline: true },
                { name: "DM:", value: `${displayText[2]}`, inline: true },
                { name: "Whereabout:", value: `${displayText[3]}`, inline: true },
                { name: "\u200B", value: "\u200B" },
                {
                    name: `<:accepted:867150417271324672>Accepted (${users1Length}/${memberCount})`,
                    value: users1Length !== 0 ? users1.join("\n") : "-",
                    inline: true,
                },
                {
