Mutation Upsert Cond does not seem to work with type checks

The variables “From” and “to” are redundant. The variables fromUID and toUID should be used instead.

As far as I know, conditional upserts supports len only.

Other way of doing it.

upsert {
  query {
		q1(func: eq(xid, "` + from.Value() + `")) @filter(eq(dgraph.type, "Entity") {
			from as uid
			dgraph.type
		}

		q2(func: eq(xid, "` + to.Value() + `")) @filter(eq(dgraph.type, "Entity") {
			to as uid
			dgraph.type
		}
	}  
  
  mutation @if(gt(len(from), 0) AND gt(len(to), 0)) {
    set {
      (...)
    }
  }
  }
