Not able to access my postgres data after running project

I've created .env file
```
TIPG_NAME="OGC Features and Tiles API - Krishna"
DATABASE_URL=postgresql://postgres:postgres@localhost:5432/postgres
```

1. I'm not able to see my layers in collection
2. and when I click on collection, I'm getting following error

Start by reproducing the project with the reported .env file and DATABASE_URL, then inspect why layers are missing from collections and why opening a collection produces the reported error. Done means the configured Postgres data appears in the collections and each collection opens without that error.
