MultiGetAsync does not infer default mapping for index

[deMD]

Elastic.Clients.Elasticsearch version: 8.13.10

Elasticsearch version: 8.4.1/8.6.1

.NET runtime version: Net 6.0

Description of the problem including expected versus actual behavior:
When calling elasticsearchclient.MultiGetAsync<TDocument>(request, cancellationToken) where the request looks like this:

var request = new MultiGetRequest { Ids = new Ids(new Id[]  { 1 }) };

A 400 Response is returned with the following message:

Elastic.Transport.TransportException: Request failed to execute. Call: Status code 400 from: POST /_mget?pretty=true&error_trace=true. ServerError: Type: action_request_validation_exception Reason: "Validation Failed: 1: index is missing for doc 0;"

Steps to reproduce:

1. Do above request to an instance of Elasticsearch with an index mapped to TDocument and a document with Id 1
   settings.DefaultMappingFor<TDocument>(x => x.IndexName("my-index"));

Expected behavior
A List with a single item is returned

Provide DebugInformation (if relevant):

Invalid Elasticsearch response built from a unsuccessful (400) low level call on POST: /_mget?pretty=true&error_trace=true
 Exception: Request failed to execute. Call: Status code 400 from: POST /_mget?pretty=true&error_trace=true. ServerError: Type: action_request_validation_exception Reason: "Validation Failed: 1: index is missing for doc 0;"

Hi @deMD,

please try to use MultiGetRequestDescriptor<TDocument> instead. The inference is usually done at descriptor creation. The request class does not support a generic type parameter and therefore has no way to determine the type of the document.

[deMD]

@flobernd This gives me the same exception:

var resp = await _client.MultiGetAsync<TDocument>(x => x
                .Ids(new Ids(new Id[]  { 1 })), 
                cancellationToken);

As you can see in this video, a searchrequest on the same index does work.

[flobernd]

Hi @deMD, I'm sorry I think I tested the wrong thing yesterday 😪

You are completely right, there is a bug in the generator that breaks the inference for descriptors that only have a required index/indices argument but not an id.

I'll take care!
