I have found same problem - #219

I tried same way, but it doesn't work for me.

Error - EntityMetadataNotFoundError: No metadata for "CategoryEntity" was found.

  //seeds: [`${ process.cwd() }/src/database/seeds/**/*{.js,.ts}`],
  //factories: [`${ process.cwd() }/src/database/factories/**/*{.js,.ts}`]
  seeds: [
    CategorySeeder
  ],
  factories: [
    CategoryFactory
  ]

@golubvladimir your problem is not directly related to this library 🙈, but it was very helpful that you could provide me with a repo to reproduce
You missed to register your database entities for the DataSource 😅

https://github.com/golubvladimir/pizza-app/blob/backend/add-seeding/backend/data-source.ts

The file should look like this:

import { DataSource, DataSourceOptions } from 'typeorm';
import { SeederOptions } from 'typeorm-extension';

console.log(process.cwd())

const options: DataSourceOptions & SeederOptions = {
  type: 'mysql',
  database: 'pizza_db',
  port: 8889,
  host: 'localhost',
  password: 'root',
  username: 'root',
  entities: [
	  'src/categories/entities/*{.js,.ts}',
	  'src/products/entities/*{.js,.ts}',
  ],
  seeds: [`src/database/seeds/**/*{.js,.ts}`],
  factories: [`src/database/factories/**/*{.js,.ts}`]
};

export const dataSource = new DataSource(options);

PS: You can also register your entities by class reference instead of path reference.

I'm having the same issue, but I'm registering by entities, :( any idea why is this happening ?

export const dataSourceOptions: DataSourceOptions & SeederOptions = {
	type: 'postgres',
	host: 'localhost',
	port: 5432,
	username: 'postgres',
	password: 'password',
	database: 'db',
	synchronize: true,

	//
	entities: ['dist/**/*.entity{.ts,.js}'],
	migrations: ['dist/db/migrations/*.js'],
	seeds: ['src/db/seeds/**/*{.ts,.js}'],
	// factories: ['db/factories/**/*{.ts,.js}'],
};

same here!

FYI: In my case, I replaced the entity path with one that included ../ and that fixed it

For example, I changed path from
import { UserEntity } from 'src/modules/user/entity/user.entity';

to
import { UserEntity } from '../../src/modules/user/entity/user.entity';
