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

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();

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?

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 am trying to make my discord bot add roles to someone that dm-ed it, and i cant seem to make it work
Here is the code:
guild.members.fetch(message.author)
.then(member => {
member.roles.set(['roleID']);
});
This is the error that i get:

Dependency :
canvas > version: 2.6.1
node > version: 12.12.62
I am trying to do bellow :
const { createCanvas, loadImage } = require('canvas');
var image = await loadImage("png.png");
But, the same piece of code is perfectly working for *.jpeg file type.
