Hi,

I am implementing the SwapAlias() function at this GitHub page: [https://github.com/elastic/elasticsearch-net-example/blob/2.x-codecomplete/src/NuSearch.Indexer/Program.cs](https://github.com/elastic/elasticsearch-net-example/blob/2.x-codecomplete/src/NuSearch.Indexer/Program.cs)

This SwapAlias() function was part of a tutorial at [https://github.com/elastic/elasticsearch-net-example/tree/2.x](https://github.com/elastic/elasticsearch-net-example/tree/2.x)

When I finally do GET /\_cat/aliases?v I don't see any aliases listed. Why is this so?

Thanks!

Hi @Edwardo_Hanna

There was [a small bug in `GetAlias()` that was fixed in NEST 2.4.4](https://github.com/elastic/elasticsearch-net/commit/994c5120f5ef3616b25489a96b491639e022982d); be sure to upgrade the version of NEST 2.x that you are using to 2.4.4.

The rest of the `SwapAlias()` implementation looks correct. Can you share how you are using it?
