RangeError [EMBED_FIELD_VALUE]: MessageEmbed 字段值必須是非空字符串

Question

所以我目前正在嘗試將我的 Discord 機器人從 V12 更新到 V13，但我目前遇到了一個非常令人沮喪的問題。 所以本質上，我正在創建一種事件命令，人們可以在其中做出反應來參加，每次有人做出反應時，嵌入編輯本身以及問題所在。 那么我是如何做到的 V12 是我通過更新值的函數編輯了消息。

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

由於錯誤的性質，我認為這不是問題的根源。 這是用於更新嵌入的代碼：

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 : "-",
            inline: true,
        },
        {
            name: `<:denied:867150431612436510>Denied (${users3.length}/${memberCount})`,
            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}`)
    .setThumbnail(

    )

    .setColor("DC143C")
    .addFields(

        { name: "Game:", value: `${displayText[1]}`, inline: true },
        { name: "Additional Notes:", value: `${displayText[2]}`, inline: true },
        { name: "\u200B", value: "\u200B" },
        {
            name: `<:accepted:867150417271324672>Accepted (${users1.length}/${memberCount})`,
            value: users1.length !== 0 ? users1 : "-",
            inline: true,
        },
        {

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

const upatedEventEmbed = new Discord.MessageEmbed()

    .setThumbnail(

    )
    .setDescription(displayText[0])
    .setColor("DC143C")
    .addFields(
        { name: "\u200B", value: "\u200B" },
        { name: "Event:", value: `${displayText[1]}`, inline: true },
        { name: "Additional Notes:", value: `${displayText[2]}`, 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 : "-",

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

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

}

此代碼在 V12 中運行良好，但現在返回錯誤：

RangeError [EMBED_FIELD_VALUE]: MessageEmbed 字段值必須是非空字符串。

編輯：所以我發現了問題，顯然你不能再將數組作為字段的值了。 這解釋了為什么這不起作用。

Answer 1

嘗試替換您設置的值

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

到

users1 || "-"

也許users1是一個array ，也許users1.length返回給你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，在創建嵌入使用之前

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

確定這些變量到底是什么。

Answer 2

根據https://discordjs.guide/additional-info/changes-in-v13.html#strings需要通過方法.toString()或模板文字進行驗證。 我的代碼沒有。 所以為了解決這個問題，我在所有用戶數組之后添加了.join("\\n") 。 這基本上用換行符拆分了數組中的所有元素。 固定代碼：

    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,
