Learning MVC, I'm trying to seed my database with dummy entries and I keep getting this error:

the following is the code used to seed my data:
const seedUsers = require('./user-seeds');
const seedPosts = require('./post-seeds');
const seedComments = require('./comment-seeds');
const seedVotes = require('./vote-seeds');
const sequelize = require('../config/connection');
const seedAll = async () => {
await sequelize.sync({ force: true });
console.log('SEQUELIZE--------------');
await seedUsers();
console.log('USERS--------------');
await seedPosts();
console.log('POSTS--------------');
await seedComments();
console.log('COMMENTS--------------');
await seedVotes();
console.log('VOTES--------------');
process.exit(0);
};
seedAll();
The error seems to occur after the seedPosts() function is called.
Would anyone be able to help?

I'm using tesseract within my node app. The first time the program runs fine.
In this example, foo() repeats it self. From the first repition on, an error is returned (shown below the code)
Could you give me a hint what I have done wrong which doesn't allow this to run a second time? I have tried to add try & catch, but it only led to more errors
const { createWorker } = require('tesseract.js');
const worker = createWorker();
function foo() {
(async () => {
await worker.load();
await worker.loadLanguage('eng');
await worker.initialize('eng');
await worker.setParameters({
tessedit_char_whitelist: '123456789'
// preserve_interword_spaces: '0',
});
const { data: { text } } = await worker.recognize('Download.png');
console.log(text);
await worker.terminate();
})();
setTimeout(foo, 10000);
}
foo();
Error message:

It works with "memes" and some other subreddits but not with "kungenavedsbyn". I'm probably really dumb but I can't figure out how to fix it.
bot.on('message', async msg => {
if (msg.content === '-örsk') {
let subreddits = [
"kungenavedsbyn"
];
let subreddit = subreddits[Math.floor(Math.random()*(subreddits.length))];
let img = await api(subreddit)
const Embed = new Discord.MessageEmbed()
.setTitle(`Här har du lite örsk`)
.setURL(`https://www.reddit.com/r/kungenavedsbyn`)
.setColor('RANDOM')
.setImage(img)
msg.channel.send(Embed)
}
});
Here's the message I get when I write the command in dc:

router.get('/:id', async (req, res) => {
const course = await Course.findById(req.params.id);
if (!course) {
return res.status(400).send(`course id is invaild`);
}
res.send(course);
});
As you guys can see, this is a very simple route function.
It works fine if it got the right id but once I gave it the wrong id it throws this error on my console

Means your bot does not have permissions to update the user's nickname. Try giving the bot those permissions and see what it does.
You'll need the MANAGE_NICKNAMES permission assigned to the bot, as per https://stackoverflow.com/a/49866239/1935718.
So I was watching youtube regarding webscraping and would like to give it a go. I tried mimicking exactly how the tutor teaches but I land into a problem right away.

Here is the sample of my codes:
const puppeteer = require('puppeteer');
async function scrapeProduct(url) {
const browser = await puppeteer.launch();
const page = await browser.newPage();
page.goto(url)
const [el] = await page.$x('//*[#id="block-1565393554829"]/div/div/div[2]/div/div[1]/a/div/img[2]');
const src = await el.getProperty('src');
const srcTxt = await src.jsonValue();
console.log({srcTxt});
}
scrapeProduct('https://shopnicekicks.com/pages/calendar');
I hope someone could teach me where I'm going wrong.
