NestJS PostgreSQL Connection Issue on Heroku

I'm facing a database connection issue with NestJS deployed on Heroku. The database I'm trying to connect to is PostgreSQL. The connection is being attempted using the ORM TypeORM.

Ideal Skills:
- Proficient in NestJS and PostgreSQL
- Experienced with Heroku deployments
- Familiar with TypeORM

Please help me resolve this issue so that I can connect my NestJS application to the PostgreSQL database on Heroku successfully.
