👋 Hey, anyone have any luck at configuring the

SPICEDB_DATASTORE_CONN_URI

environment variable to refer to other environment variables for expansion? Seems to work for the db migration command but not when actually starting up spicedb serve. I'm connecting to cockroachdb and have the following format

postgres://<username>:$DB_PASSWORD@$DB_HOST:26257/defaultdb

but it fails with the following error.

unable to instantiate datastore: error acquiring connection from pool: failed to connect to host=$DB_HOST user=svc-spicedb database=: hostname resolving error (lookup $DB_HOST: no such host)
