According to the documentation,
uid_in cannot accept a variable as the value for uid.
Is there a way, in a single call to dgraph (multiple queries, one network call), to find the relevant node using a different predicate, for example
@filter(eq(name,"Bob")) then filter other nodes based on the uid of Bob. Or must I always do two calls to DGraph in order to fetch the nodes that have Bob in one of their recursive relations?
