[SOLVED] How to solve asyncpg.exceptions.InvalidAuthorizationSpecificationError

I'm going through the course Test-Driven Development with FastAPI and Docker from testdriven.io and just stucked with releasing my app to heroku (Part 2: Deployment). Everything was fine before I released the image to heroku:

heroku container:release web --app APP_NAME

Then I checked the https://APP_NAME.herokuapp.com/ping/ endpoint and got

503 Service Unavailable.

Need help. I found such tracebacks in heroku logs --tail:
