Discord. Js Invalid Form Body [Duplicate]

At the time I am trying to learn how to make a discord bot and I got an error I dont know waht it means or how to fix it. I made a command for welcome messages with a youtube tutorial and now it stopped working.

Error:

DiscordAPIError[50035]: Invalid Form Body
7.options[0].name[APPLICATION_COMMAND_INVALID_NAME]: Command name is invalid

Code:

const {Message, Client, SlashCommandBuilder, PermissionFlagsBits} = require("discord.js");
const welcomeSchema = require("../../Models/Welcome");
const {model, Schema} = require("mongoose");

module.exports = {
    name:"setup-welcome",
    description:"Set up your welcome message for the discord bot.",
    UserPerms:["BanMembers"],
    category:"Moderation",
    options: [
        {
            name:"Channel",
            description:"Channel for welcome messages.",
            type:7,
            required:true
        },

        {
            name:"welcome-message",
            description:"Enter your welcome message.",
            type:3,
            reqired:true
        },

        {
            name:"welcome-role",
            description:"Enter your welcome role.",
            type:8,
            required:true
        }
    

    ],
                
    async execute(interaction) {
        const {channel, options} = interaction;

        const welcomeChannel = options.getChannel("channel");
        const welcomeMessage = options.getString("welcome-message");
        const roleId = options.getRole("welcome-role");

        if(!interaction.guild.members.me.permissions.has(PermissionFlagsBits.SendMessages)) {
            interaction.reply({content: "I don't have permissions for this.", ephemeral: true});
        }

        welcomeSchema.findOne({Guild: interaction.guild.id}, async (err, data) => {
            if(!data) {
                const newWelcome = await welcomeSchema.create({
                    Guild: interaction.guild.id,
                    Channel: welcomeChannel.id,
                    Msg: welcomeMessage,
                    Role: roleId.id
                });
            }
            interaction.reply({content: 'Succesfully created a welcome message', ephemeral: true});
        })
    }
}

I tried a few things like changing the construction of the bot or change some thing like the command options.
Thanks in advance!
