值保存为数组而不是字符串

Question

我的值在 mongodb 中保存为数组，但我想作为字符串

这是代码

          input(name='mutedRole', type='hidden', value='')
          select.form-control(name='mutedRole', single)
            each role of Array.from(guild.roles.cache.filter(r => r.name != '@everyone').values())
              if savedGuild.moderation.mutedRole.includes(role.id)
                option(value=role.id, selected) #{role.name}
              else
                option(value=role.id) #{role.name}
