Why does Canton reject my postgres configuration?

Hi all,

I’m trying to set up a small test Canton network with a simple configuration, but my postgres configuration is getting rejected because it is expecting a string for the storage, not an object. Please can you tell me where I’m going wrong?

_shared {
  storage {
    type = postgres
    config {
      dataSourceClass = "org.postgresql.ds.PGSimpleDataSource"
      properties = {
        serverName = "localhost"
        portNumber = "5432"
        user = "admin"
        password = "password"
      }
    }
  }
}
canton {
  participants {
    agent {
      storage.type = ${_shared.storage}
      storage.config.properties.databaseName = "contractStore"
      admin-api.port = 5012
      ledger-api.address = 0.0.0.0
      ledger-api.port = 5011
    }
  }
  domains {
    mydomain {
      storage.type = memory
      public-api.port = 5018
      admin-api.port = 5019
    }
  }
  features.enable-testing-commands = yes
}

With error:

ERROR c.d.c.CantonCommunityApp$ - GENERIC_CONFIG_ERROR(8,0): Cannot convert configuration to a config of class com.digitalasset.canton.config.CantonCommunityConfig. Failures are:
  at 'canton.participants.agent.storage.type':
    - (azure.conf: 2) Expected type STRING. Found OBJECT instead.

You’re setting storage.type to the object that should be the whole storage not just the storage type. Try something like

storage = ${_shared.storage}
