What happened?

Followed the Snowball token filter example to create an English custom analyzer for a property on a new index. I have noted the request/response:

Request:
PUT /my-index-00001

Additional info

I am running Elasticsearch 8.9.0 according to my research there should not be a plugin necessary to use snowball analysis.
