What happened?

List what you are trying to do?

I am trying to setup AdminJS with mikro-orm. Following the documentation I tried using:

const mikroOrmConfig: any =
{
	entities: [Event, Config],
	dbName: "dbname",
	user: "user",
	password: "****",
	type: 'postgresql',
	host: "db",
	port: 5432,
	debug: true,
	extensions: [SeedManager],
}

However, this results in the following error:

Error: The `type` option has been removed in v6, please fill in the `driver` option instead or use `defineConfig` helper (to define your ORM config) or `MikroORM` class (to call the `init` method) exported from the driver package (e.g. `import { defineConfig } from '@mikro-orm/mysql'; export default defineConfig({ ... })`).

    at async initORM (file:///app/src/db.ts:10:17)
    at async Namespace.<anonymous> (file:///app/src/configs.ts:9:20)

When I try using the required field driver like:

const mikroOrmConfig: any =
{
	entities: [Event, Config],
	dbName: "dbname",
	user: "user",
	password: "****",
	driver: PostgreSqlDriver,
	host: "db",
	port: 5432,
	debug: true,
	extensions: [SeedManager],
}

this results in a different error of:

Unable to connect to the database: NoDatabaseAdapterError: There are no adapters supporting one of the database you provided

    },
    em: [EntityManager<1>],
    event: SqlEntityRepository { em: [EntityManager<1>], entityName: 'Event' }
  }
}
