map函数中缺少花括号。该函数应如下所示

const songs = [
   {
     name: 'Song 1',
     formattedDuration: 2
   },
   {
     name: 'Song 2',
     formattedDuration: 5
   },
   {
     name: 'Song 3',
     formattedDuration: 6
   }
]

const menu = new SelectMenuBuilder()
      .setCustomId('select')
      .setPlaceholder('Nothing selected')
      .addOptions(songs.map(song => { return {label: song.name, description: song.formattedDuration }}))

值应该是字符串的形式，而不是整型或双精度型，不管你给的是什么，都要对它们使用toString（）。

const row = new ActionRowBuilder().addComponents(
            new StringSelectMenuBuilder()
                .setCustomId('select')
                .setPlaceholder('Nothing selected')
                .addOptions(
                    adana.map(function (curentValue, index) {
                        return {
                            label: index.toString(),
                            value: index.toString(),
                        }
                    })
                )
        )
