This is my model class:
final case class Organization(
id: UUID,
name: String
)
My Queries class looks like this:
case class Queries(
organizations: URIO[DatabaseService, List[Organization]]
)
And I have a service that looks like this:
class GraphQLService:
def getOrganizations =
for
db <- ZIO.service[DatabaseService]
orgs <- db.organizations
yield orgs
val queries = Queries(getOrganizations.orDie)
val resolver = RootResolver(queries)
val api = graphQL(resolver)
db.organizations returns ZIO[Any, SQLException, List[Organization]].
That last line gets the following error:
Cannot find a Schema for type zio.URIO[io.livefeeds.db.DatabaseService,
List[io.livefeeds.db.model.Organization]
].
Caliban derives a Schema automatically for basic Scala types, case classes and sealed traits, but
you need to manually provide an implicit Schema for other types that could be nested in zio.URIO[io.livefeeds.db.DatabaseService,
List[io.livefeeds.db.model.Organization]
].
If you use a custom type as an argument, you also need to provide an implicit ArgBuilder for that type.
See https://ghostdogpr.github.io/caliban/docs/schema.html for more information.
.
I found:
caliban.schema.Schema.gen[Any,
zio.ZIO[io.livefeeds.db.DatabaseService, Nothing,
List[io.livefeeds.db.model.Organization]
]
]
But given instance gen in trait SchemaDerivation does not match type caliban.schema.Schema[Any,
zio.URIO[io.livefeeds.db.DatabaseService,
List[io.livefeeds.db.model.Organization]
]
].
val api = graphQL(resolver)
As far as I can tell, I'm not using anything unsupported. The docs say that ZIO[R, Nothing, A] maps to A. What am I missing?
