Reproduction

Steps to reproduce

I'm using NestJs.

Configure your package.json like this:

"seed": "ts-node ./node_modules/typeorm-extension/dist/cli/index.js seed -- -d src/database/database.config.ts"

Add a database.config.ts under src/database in your project with the following code:

import { DataSource, DataSourceOptions } from 'typeorm';
import { ConfigService } from '@nestjs/config';
import { config } from 'dotenv';
import { SeederOptions } from 'typeorm-extension';

config();

const configService = new ConfigService();

const options: DataSourceOptions & SeederOptions = {
  type: 'mysql',
  host: configService.get<string>('MYSQL_HOST'),
  port: configService.get<number>('MYSQL_PORT'),
  username: configService.get<string>('MYSQL_USER'),
  password: configService.get<string>('MYSQL_PASSWORD'),
  database: configService.get<string>('MYSQL_DB_NAME'),
  entities: ['dist/**/*.entity{.ts,.js}'],
  migrations: ['dist/migrations/**/*{.ts,.js}'],
  timezone: 'Z',
  logging: true,
  migrationsRun: true,
  synchronize: false,
  ssl: {
    rejectUnauthorized: false,
  },
  seeds: ['src/database/seeds/**/*{.ts,.js}'],
  factories: ['src/database/factories/**/*{.ts,.js}'],
};

export const AppDataSource = new DataSource(options);

Now, if you run the seed script the following error will occur:

TypeORMError: No connection options were found in any orm configuration files.
    at ConnectionOptionsReader.all (/home/jph/zenbit/HiveIn_be/node_modules/src/connection/ConnectionOptionsReader.ts:46:19)
    at async ConnectionOptionsReader.get (/home/jph/zenbit/HiveIn_be/node_modules/src/connection/ConnectionOptionsReader.ts:58:28)

What is Expected?

It would be expected to connect with the database, if I change the file to data-source.ts it will find the connection file.

What is actually happening?

Can't run the CLI script if I have a configuration file with a name that isn't data-source.ts
