no need for this local, just call directly
IndexedDBKeyUtilityClient::GetInstance()->Create...
below:

Done.

   size_t size = values.size();
   std_values.reserve(size);
   for (size_t i = 0; i < size; ++i)

   std::vector<IndexedDBKey> std_keys;
-  indexed_db_key_utility_client_->CreateIDBKeysFromSerializedValuesAndKeyPath(
+  key_utility_client->CreateIDBKeysFromSerializedValuesAndKeyPath(
       std_values, keyPath, &std_keys);
 
   keys = std_keys;
