Could not load seeders!

Sorry, I cannot work just with an image without any context.

Please, try to create a reproducible example in a repo, or at least, a decent amount of code.

I ran into the same issue, I debugged it: the problem is that the "run" method receives the following array as paths: [ 'seed', './seed/0_clear.ts', './seed/1_create_users.ts', ... ]

@jagoanmamah did you have a seed folder too? Based on the image your case can be a different one.

The root cause is that the seed command is prepended to the paths array (maybe the "commander" package is misused) and if you store the seeds under a folder named "seed" you can see this error message because we try to load the module from that folder.

I figured out two workarounds, both of them are working independently:

1. Remove the "seed" command when calling the CLI (for me it's something like that: ts-node -r tsconfig-paths/register ./node_modules/@jorgebodega/typeorm-seeding/dist/cli.js -d ./data-source.ts ./seed/*.ts)
2. Rename the "seed" folder to something else, for example "seeders": (for me it's something like that: ts-node -r tsconfig-paths/register ./node_modules/@jorgebodega/typeorm-seeding/dist/cli.js seed -d ./data-source.ts ./seeders/*.ts)

I don't have time to fix this issue and send a PR but I hope these informations are going to help you!

// create-admin.seed.ts

import { DataSource } from 'typeorm';
import * as bcrypt from 'bcrypt';
import { Admin } from 'src/modules/admin/entities/admin.entity';
import { EAdminRole } from 'src/modules/admin/types/admin.types';
import { Seeder } from '@jorgebodega/typeorm-seeding';

export default class AdminSeeder extends Seeder {
  async run(dataSource: DataSource) {
    console.log('Seeding admin\n\n\n');
    // Hash the password
    const saltRounds = 10;
    const hashedPassword = await bcrypt.hash('password', saltRounds);

    // Create new admin
    const admin = new Admin();
    admin.firstName = 'Admin';
    admin.lastName = 'User';
    admin.email = 'admin@example.com';
    admin.phoneNumber = '+234700000000';
    admin.hashedPassword = hashedPassword;
    admin.role = EAdminRole.SUPER_ADMIN;

    await dataSource.createEntityManager().save<Admin>([admin]);
  }
}

following the first workaround @6uliver mentioned, I was finally able to go past the initial error

yarn seed:run

But I came across a different error:

Any idea where the metadata mentioned in the error should be defined?
