NoMethodError: undefined method `find' for nil:NilClass

In production, we can't search in multiple models. it works fine locally.

Elasticsearch version v7.4.2

    search_payload = {
      query: {
        bool: {
          must: [
            {
              multi_match: {
                query: params[:search].to_s.downcase
              }
            }
          ],
          must_not: {
            exists: {
              field: 'deleted_at'
            }
          },
          filter: [
            {
              term: {
                user_: user_shop.id,
              }
            }
          ]
        }
      },
      size: 7
    }

records = Elasticsearch::Model.search(search_payload, [Order, Product]).records
records.json

I am also running into this bug. I tracked it down to a failure to match __type_for_hit in vendor/bundle/gems/elasticsearch-model-7.1.1/lib/elasticsearch/model/adapters/multiple.rb:109

In our case we use index aliases so model.index_name == hit[:_index] will never be true. Also seems like with ElasticSearch deprecating the _type and document_type fields this will need to be reworked before ES 8 support is added.
