Prisma

Got some logs. Seems like some issue with config but it looks ok to me. `Could not resolve substitution to a value: ${SCHEMA_MANAGER_SECRET}`

<@U8L2D9TMJ> I’m just following the tutorial and I see it in the .env file here:
```
PORT=4466
CLUSTER_ADDRESS=<http://prisma-database:${PORT}>

SQL_CLIENT_HOST=prisma-db
SQL_CLIENT_PORT=3306
SQL_CLIENT_USER=root
SQL_CLIENT_PASSWORD=__SECRET_2__
SQL_CLIENT_CONNECTION_LIMIT=10

SQL_INTERNAL_HOST=prisma-db
SQL_INTERNAL_PORT=3306
SQL_INTERNAL_USER=root
SQL_INTERNAL_PASSWORD=__SECRET_2__
SQL_INTERNAL_DATABASE=graphcool
SQL_INTERNAL_CONNECTION_LIMIT=10

SCHEMA_MANAGER_SECRET=SECRET_1
SCHEMA_MANAGER_ENDPOINT=<http://prisma-database:${PORT}/cluster/schema>
