Upsert with multiple UIDs

When I use:

{
  getVals(func: has(products)) {
    productsUid as uid
  	products @filter(eq(productId, 19610626)) {
      productUid  as uid
      options @filter(eq(optionId, 32661491)) {
        optionUid as uid
      }
    }
  }
}

I still get:

io.grpc.StatusRuntimeException: UNKNOWN: while parsing query: “{\n getVals(func: has(products)) {\n productsUid as uid\n \tproducts @filter(eq(productId, 19610626)) {\n productUid as uid\n options @filter(eq(optionId, 32661491)) {\n optionUid as uid\n }\n }\n }\n}”: Some variables are defined but not used
