SearchAsYouTypeProperty: Unknown field 'doc_values' (JSON path: mappings.properties.search_as_you_type.doc_values

Problem description

Given an index with properties

"search_as_you_type": {
        "type": "search_as_you_type",
        "analyzer": "default",
        "doc_values": false
      }

I am able to post it to the server from Kibana:

But the client fails to post it:

[ERROR]   JsonpMapping Error deserializing co.elastic.clients.elasticsearch._types.mapping.SearchAsYouTypeProperty: Unknown field 'doc_values' (JSON path: mappings.properties.search_as_you_type.doc_values) (in object at line no=52, column no=30, offset=1208)

Hello and thank you for reporting this. This is a special case, since search_as_you_type actually doesn't support doc_values as a request field, but the server always includes it as "false" in the response. I'll investigate a bit to understand how we want to handle this!

That's interesting because it allowed me to set it to false when I created the index, which gave me the illusion that it was possible to set it

If setting it shouldn't be possible, it should probably fail, I believe

Also, I think that the docs https://www.elastic.co/guide/en/elasticsearch/reference/current/doc-values.html should be updated to include this limitation as it currently says

Doc values are supported on almost all field types, with the notable exception of text and annotated_text fields.

Good catch, if this is confirmed then we'll also update the docs.
