External database password not working as expected

[ngc4579]

The configuration for an external database as explained in the README does not seem to work:

---
config:
  dbHost: postgres.example.com
  dbPort: 5432
  dbName: mydatabase
  dbUsername: myusername
  dbPassword: env:POSTGRES_DB_PASSWORD

server:
  env:
    - name: POSTGRES_DB_PASSWORD
      valueFrom:
        secretKeyRef:
          name: mysecret
          key: mypassword

Starting the server with an accordingly prepared secret does not work (bad credentials). This does not occur when inserting the password into the values.yaml directly:

config:
  ...
  dbPassword: <somePassword>

It seems the server does not evaluate the prefix env: in order to use the mentioned environment variable instead of a string literal.

I also have faced it
Seem unrelated to Helm Chart though, the string are passed correctly to the app via configmap, but are not parsed properly
