NestJS TypeORM syntax error in migration file

Question

I was going through the NestJS official docs. I set up PostgreSQL on Heroku, connected with TypeORM, run a migration and after that my app started crushing. I tried different approaches and searched blogs/issues on github/questions here, but nothing helped.

Here is an error:

[Nest] 46723   - 05/10/2020, 6:33:42 PM   [InstanceLoader] TypeOrmModule dependencies initialized +84ms
[Nest] 46723   - 05/10/2020, 6:33:43 PM   [TypeOrmModule] Unable to connect to the database. Retrying (1)... +493ms

import {MigrationInterface, QueryRunner} from "typeorm";

Here is my ormconfig.json:

  "type": "postgres",
  "url": "postgres://***",
  "ssl": true,
  "extra": {
    "ssl": {
      "rejectUnauthorized": false
    }
  },
  "entities": ["dist/**/*.entity{.ts,.js}"],
  "migrationsTableName": "custom_migration_table",
  "migrations": ["migration/*{.ts,.js}"],
  "cli": {
    "migrationsDir": "migration"
  }
}

migration was generated using ts-node ./node_modules/.bin/typeorm migration:generate -n AddUser I'm using nest start --watch command to start the app.

Migration file {TIMESTAMP}-AddUser.ts:

import {MigrationInterface, QueryRunner} from "typeorm";

export class AddUser1589119433066 implements MigrationInterface {
    name = 'AddUser1589119433066'

    public async up(queryRunner: QueryRunner): Promise<void> {
        await queryRunner.query(`CREATE TABLE "users" (...)`, undefined);
    }

    public async down(queryRunner: QueryRunner): Promise<void> {
        await queryRunner.query(`DROP TABLE "users"`, undefined);
    }

}

Thanks to @Isolated! I've changed the ormconfig.json so entities and migrations files looks like this now and it works fine for me:

"entities": ["dist/**/*.entity{.ts,.js}"],
"migrations": ["dist/migration/*{.ts,.js}"],
