how can i solve the problem with slash im discord.js?

Question

my bot worked until yesterday, but I updated it and put some new commands and now this error appears ,when I click for my bot to start this error appears: Reason: DiscordAPIError[50035]: Invalid Form Body 2.options[0].type[NUMBER_TYPE_COERCE]: Value "integer" is not int. and this appears in all bot slashed commands

here the codes of one of the bot screens:

const { getVoiceConnection } = require("@discordjs/voice");
module.exports = {
name: "volume",
description: "Changes the Volume of the Music",
options: [
{
  name: "volume",
  description: "Then Volume you want to set",
  type: "INTEGER",
  required: true,
},
],
run: async (client, interaction, args, prefix) => {
if (!interaction.member.voice.channelId)
  return interaction
    .reply({
      ephemeral: true,
      content: "👎 **Please join a Voice-Channel first!**",
    })
    .catch(() => null);
// get an old connection
const oldConnection = getVoiceConnection(interaction.guild.id);
if (!oldConnection)
  return interaction.reply({
    ephemeral: true,
    content: "👎 **I'm not connected somewhere!**",
  });
if (
  oldConnection &&
  oldConnection.joinConfig.channelId != interaction.member.voice.channelId
)
  return interaction
    .reply({
      ephemeral: true,
      content: "👎 **We are not in the same Voice-Channel**!",
    })
    .catch(() => null);

const queue = client.queues.get(interaction.guild.id); // get the queue
if (!queue) {
  return interaction.reply({
    ephemeral: true,
    content: `👎 **Nothing playing right now**`,
  });
}
if (
  !args[0] ||
  isNaN(args[0]) ||
  Number(args[0]) < 1 ||
  Number(args[0]) > 150
)
  return interaction
    .reply({
      ephemeral: true,
      content: `👎 **No __valid__ Volume between 1 and 100 % provided!** Usage: \`${prefix}volume 25\``,
    })
    .catch(() => null);
const volume = Number(args[0]);
queue.volume = volume;

// change the volume
oldConnection.state.subscription.player.state.resource.volume.setVolume(
  volume / 100
);

return interaction
  .reply({
    ephemeral: false,
    content: `🔊 **Successfully changed the Volume to \`${volume}%\`**`,
  })
  .catch(() => null);
  },
  };

You have to use the enums in v14. In this case, ApplicationCommandOptionType

const { ApplicationCommandOptionType } = require("discord.js")
// ...
  {
    // ...
    type: ApplicationCommandOptionType.Integer
  }
