javascript - How to fix this error I am getting with my discord bot

Question

This is my reactionrole.js file, I am getting an error and have no idea how to fix this, I am new to javascript coding in general, I have a command handler for the bot instead of putting all my commands in my main.js file (it previously was all in the main.js file). I moved all the commands to their own files to try make the main.js smaller, all other features of my bot are working after doing so but not my reaction roles.

module.exports = {
    name: 'reactionrole',
    description: 'Sets up a reaction role message.',
    async execute(message, args, Discord, client) {
        const channel = '802539365985157141';
        const yellowTeamRole = message.guild.roles.cache.find(role => role.name === "test");
        const blueTeamRole = message.guild.roles.cache.find(role => role.name === "test2");

        const yellowTeamEmoji = '??';
        const blueTeamEmoji = '??';

        let embed = new Discord.MessageEmbed()
            .setColor('#e42643')
            .setTitle('Choose a team to play on!')
            .setDescription('Choosing a team will allow you to interact with your teammates!

' +
                `${yellowTeamEmoji} for yellow team
` +
                `${blueTeamEmoji} for blue team`);

        let messageEmbed = await message.channel.send(embed);
        messageEmbed.react(yellowTeamEmoji);
        messageEmbed.react(blueTeamEmoji);

        client.on('messageReactionAdd', async (reaction, user) => {
            if (reaction.message.partial) await reaction.message.fetch();
            if (reaction.partial) await reaction.fetch();
            if (user.bot) return;
            if (!reaction.message.guild) return;

            if (reaction.message.channel.id == channel) {
                if (reaction.emoji.name === yellowTeamEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.add(yellowTeamRole);
                }
                if (reaction.emoji.name === blueTeamEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.add(blueTeamRole);
                }
            } else {
                return;
            }

        });

        client.on('messageReactionRemove', async (reaction, user) => {

            if (reaction.message.partial) await reaction.message.fetch();
            if (reaction.partial) await reaction.fetch();
            if (user.bot) return;
            if (!reaction.message.guild) return;


            if (reaction.message.channel.id == channel) {
                if (reaction.emoji.name === yellowTeamEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.remove(yellowTeamRole);
                }
                if (reaction.emoji.name === blueTeamEmoji) {
                    await reaction.message.guild.members.cache.get(user.id).roles.remove(blueTeamRole);
                }
            } else {
                return;
            }
        });
    }


}

Trying to make reaction roles for my discord bot but it's throwing this error when I use the command.

Answer 1

I was executing client at the end instead of executing it first..

Issue:

module.exports = {
name: 'reactionrole',
description: 'Sets up a reaction role message.',
async execute(Discord, message, args, client)

Solution:

module.exports = {
name: 'reactionrole',
description: 'Sets up a reaction role message.',
async execute(client, message, args, Discord)
