How to stop commands when breaking when :"overloaded" - discord

Question

I have a few commands that follow this same code, just some things changed, the code is for -dog command, which works fine within moderation (not spamming the command, maybe running it every 5 seconds) but when it does get spammed it will often spit a odd error into the terminal, I was wondering if there is anyway to fix this or improve it. Thanks!
Language: Discord.js V12
const Discord = require('discord.js');
const url = 'https://www.reddit.com/r/lookatmydog/hot/.json?limit=100'
module.exports = {
name: 'dog',
description: 'sends a dog!',
execute(message, args) {
https.get(url, (result) => {
var body = ''
result.on('data', (chunk) => {
body += chunk
})
result.on('end', () => {
var response = JSON.parse(body)
var index = response.data.children[Math.floor(Math.random() * 99) + 1].data
if (index.post_hint !== 'image') {
var text = index.selftext
const textembed = new Discord.MessageEmbed()
.setTitle(subRedditName)
.setColor('RANDOM')
.setDescription(`[${title}](${link})\n\n${text}`)
.setURL(`https://reddit.com/${subRedditName}`)
message.channel.send(textembed)
}
var image = index.preview.images[0].source.url.replace('&', '&')
var link = 'https://reddit.com' + index.permalink
var subRedditName = index.subreddit_name_prefixed
if (index.post_hint !== 'image') {
const textembed = new Discord.RichEmbed()
.setTitle(subRedditName)
.setColor('RANDOM')
.setDescription(`[${title}](${link})\n\n${text}`)
.setURL(`https://reddit.com/${subRedditName}`)
message.channel.send(textembed)
}
console.log(image);
const imageembed = new Discord.MessageEmbed()
.setTitle('Here is a dog, how nice!')
.setImage(image)
.setColor('RANDOM')
message.channel.send(imageembed)
}).on('error', function (e) {
console.log('Got an error: ', e)
})
})
},
}```
The error I got writing this was:
```C:\Users\-\Desktop\Corn Flakes\commands\Fun\dog.js:26
.setDescription(`[${title}](${link})\n\n${text}`)
